The Pensilvaniya temir yo'li (hisobot belgisi PRR, qonuniy nomi Pensilvaniya temir yo'l kompaniyasi, "nomi bilan ham tanilganPensi") amerikalik edi I sinf temir yo'l 1846 yilda tashkil etilgan va uning bosh qarorgohi Filadelfiya, Pensilvaniya. Yilda tashkil etilganligi sababli shunday nomlangan Pensilvaniya Hamdo'stligi.

1882 yilga kelib, Pensilvaniya temir yo'li eng katta temir yo'lga aylandi (trafik va daromad bo'yicha), eng yirik transport korxonasi va dunyodagi eng yirik korporatsiyaga aylandi. Uning byudjeti AQSh hukumatidan keyin ikkinchi o'rinda turardi.[1] Korporatsiya eng uzoq davom etgan dividendlar tarixidagi rekordni saqlab kelmoqda: 100 yildan ortiq vaqt davomida aktsiyadorlarga yillik dividendlar to'lab kelgan.[2]

Ko'p yillar davomida u kamida 800 ta boshqa temir yo'l liniyalari va kompaniyalarini sotib oldi, birlashtirdi yoki ularga tegishli bo'ldi.[3] 1926 yil oxirida u 11 640,66 milya (18 733,83 kilometr) temir yo'l liniyasini boshqargan;[1-qayd][4] o'tgan asrning 20-yillarida, xuddi shunga o'xshash uzunlikdagi boshqa temir yo'llardan deyarli uch baravar ko'p transport o'tkazgan Birlik Tinch okeani va Atchison, Topeka va Santa Fe temir yo'llar. Uning yagona dahshatli raqibi Nyu-York Markaziy (NYC), bu Pensining tonna millarining to'rtdan uch qismini tashiydi.

1968 yilda Pensilvaniya temir yo'li raqibini o'ziga singdirdi Nyu-York markaziy temir yo'li va oxir-oqibat temir yo'l nomi bilan ketdi Penn Markaziy transport kompaniyasi, yoki qisqacha "Penn Central", temir yo'l ikki yil ichida bankrot deb e'lon qildi.[5]:1-bob

Bankrotlik davom etdi va 1976 yil 1 aprelda temir yo'l temir yo'l aktivlarini va boshqa bir qator ishlamay qolgan shimoliy-sharqiy temir yo'llarning aktivlarini yangi temir yo'lga topshirdi. Konsolidatsiyalangan temir yo'l korporatsiyasi yoki qisqacha Conrail. Conrail o'zi sotib olingan va 1999 yilda tizimning 58 foizini Norfolk janubiy temir yo'liga (NS), shu jumladan qolgan deyarli barcha sobiq Pensilvaniya temir yo'llariga yo'naltirgan holda ajratilgan. AQShning Amtrak yo'lovchi tashuvchisi elektrlashtirilgan segmentini oldi Asosiy yo'nalish Harrisburgning sharqida.

1976 yildan so'ng, temir yo'l oxir-oqibat sug'urta kompaniyasiga aylandi va endi nomi bilan yuritiladi Amerika Premier Anderrayterlari va hozirda uning filiali hisoblanadi Amerika moliyaviy guruhi.

Boshlanish

Ning ochilishi bilan Eri kanali 1825 yilda va boshlanishi Chesapeake va Ogayo kanali 1828 yilda Filadelfiya biznes manfaatlari Filadelfiya porti trafikni yo'qotib qo'yishidan xavotirga tushdi. Shtat qonun chiqaruvchisi Pensilvaniya bo'ylab kanal qurish uchun bosim o'tkazdi va shu tariqa Jamoat ishlarining asosiy yo'nalishi 1826 yilda foydalanishga topshirilgan.[6] Tez orada bitta kanal amaliy bo'lmasligi aniq bo'ldi va bir qator temir yo'llar, moyil samolyotlar va kanallar taklif qilindi.[7] Marshrut Filadelfiya va Kolumbiya temir yo'lidan, Susquehanna va Juniata daryolari bo'yidagi kanallardan, moyil samolyot temir yo'li deb nomlangan Allegheny Portage temir yo'li, bo'ylab tunnel Allegheny tog'lari va Konemo va Allegeniy daryolari bo'ylab Ohayo daryosidagi Pensilvaniya shtatidagi Pitsburgga boradigan kanallar; 1834 yilda qurib bitkazilgan. Yuk va yo'lovchilar marshrut bo'ylab bir necha marta vagonlarini almashtirishlari kerak bo'lganligi va qishda qishda ariqlar muzlab qolganligi sababli, tez orada tizim noqulayligi va undan yaxshi yo'l kerakligi ayon bo'ldi.[7][8]

1846 yilda Pensilvaniya qonun chiqaruvchisiga ikkita murojaat qilingan edi. Birinchisi, Pensilvaniya temir yo'l kompaniyasi deb nomlangan yangi temir yo'l uchun temir yo'l qurilishi kerak edi. Harrisburg va Pitsburg, Pensilvaniya. Ikkinchisi Baltimor va Ogayo temir yo'llari (B&O), Pittsburgga Merilend shtatidagi Kamberlenddan qurmoqchi bo'lgan. Ikkala ariza ham shartlar asosida qondirildi. Agar Pensilvaniya temir yo'li bir yil ichida etarlicha temir yo'l qurish uchun etarli mablag 'va shartnoma tuzmagan bo'lsa, u holda B&O hisobi kuchga kirar va Pensining bekor bo'lib, shu bilan B&O ning Pensilvaniya va Pitsburgga borishiga imkon yaratadi. Pensilvaniya temir yo'l kompaniyasi talablarni bajardi va Patent xatlari 1847 yil 25-fevralda Pensilvaniya gubernatori tomonidan chiqarilgan. Gubernator keyingi avgustda B & O ning huquqlarini bekor qildi.[4]

Dastlabki yillar

1847 yilda Pensni direktorlari tanladilar J. Edgar Tomson, dan muhandis Gruziya temir yo'li, chiziqni o'rganish va qurish uchun. U Susquehanna daryosining g'arbiy qirg'og'idan Juniata daryosiga tutashgan joyga qarab, Allegheny tog'lari etagiga etib borguncha, uning qirg'oqlarini kuzatib boradigan yo'lni tanladi. Oltona, Pensilvaniya.[7] Tog'larni bosib o'tish uchun chiziq o'rtacha darajaga ko'tarilib, 10 mil (16 km) gacha bo'lgan masofani to'ldirgandan so'ng ikkita tog'li jarlikning bo'linishiga etib bordi va yo'llar 220 graduslik egri chiziq bilan ko'tarilib to'ldirdi. Nal egri chizig'i bu sinfni 2 foizdan kamiga cheklab qo'ydi. Tog'ning tepasiga 1,110 m 3,612 fut Gallitzin tunnellari va keyin o'rtacha darajaga tushib, Jonstaunga tushishdi.

Chiziqning g'arbiy uchi bir vaqtning o'zida Pitsburgdan, sharqqa qarab Allegeniy va Konemo daryolari bo'ylab Jonstaungacha, sharqiy uchi esa Harrisburgdan Oltunagacha qurilgan. 1848 yilda Pensien kompaniyasi bilan shartnoma tuzdi Harrisburg, Portsmut, Mountjoy va Lankaster temir yo'li (HPMtJ & L) Xarrisburgdan sharqiy Lancastergacha xizmat ko'rsatuvchi ikkala yo'l bo'ylab uskunalarni sotib olish va ulardan foydalanish uchun.[4] 1851 yilda Pitsburg va Jonstaun o'rtasida yo'llar qurib bitkazildi. 1852 yilda Filadelfiya va Pitsburg o'rtasida bir nechta tashkilotning, shu jumladan Pensilvaniya temir yo'lining uzluksiz temir yo'l liniyasi ochildi. 1853 yilda Pensilvaniya berildi kuzatuv huquqlari Filadelfiya va Kolumbiya orqali, ikki shahar o'rtasidagi aloqani ta'minlab, Lancaster va Columbia-dagi HPMtJ & L bilan bog'langan.[4] 1854 yilga kelib, Pensilvaniya Allegheny Portage temir yo'lining moyil samolyotlaridan foydalanishni bekor qilib, Harrisburgdan Pitsburggacha bo'lgan yo'nalishni yakunladi.

1857 yilda PRR Pensilvaniya shtatidan jamoat ishlari asosiy yo'nalishini sotib oldi. Ushbu xarid 275 milya (443 km) kanalni, Filadelfiya va Kolumbiya temir yo'lini va Yangi portaj temir yo'lini (hozirgi tark qilingan Allegheny Portage temir yo'lining o'rnini egallagan) o'z ichiga olgan.[4] Pensilvaniya Yangi Portage temir yo'lining katta qismini 1857 yilda tark etdi, chunki u endi Pensilvaniya temir yo'lining o'z yo'nalishi bilan keraksiz edi. 1861 yilda Pensilvaniya HPMtJ & L-ni Pitsburg va Filadelfiya o'rtasidagi butun yo'lni o'z nazorati ostiga olish uchun ijaraga oldi.

Johnstown-dan Pitsburggacha bo'lgan kanal 1865 yilda tashlab qo'yilgan va qolgan kanallar Pensilvaniya kanali kompaniyasi 1866 yilda.[4]

Asosiy yo'nalish paydo bo'lganidan boshlab dublyaj edi va asrning oxiriga kelib uchinchi va to'rtinchi yo'l qo'shildi. Keyingi 50 yil ichida Pensilvaniya boshqa temir yo'llarni aktsiyalarni sotib olish va 999 yillik ijaraga olish orqali nazoratini qo'lga kiritish orqali kengaytirildi.[8] Faoliyatining birinchi yilining oxirida Pensilvaniya temir yo'li dividend to'ladi va dividendni 1946 yilgacha uzilishsiz davom ettirdi.

Kengayish

Pensilvaniya temir yo'l tizimi xaritasi, 1893 y

Pensining nizomi 1853 yil 23 martda to'ldirilgan bo'lib, unga boshqa shtatlarda kapital aktsiyalarining foizigacha aktsiyalarni sotib olish va temir yo'l zayomlarini kafolatlash imkoniyati berildi. Keyin qo'shimcha trafikni ta'minlash umidida Pensi bir necha qatorlarga yordam berdi. 1854 yil oxiriga kelib, Pensien Ogayo va Pensilvaniya, Ogayo va Indiana, Marietta va Sincinnati, Meysvill va Big Sendi va Sprinfildda tog'larni sotib oldi. Vernon va Pitsburg temir yo'llari, umumiy qiymati 1 450 000 dollar (2019 yilda 41,3 million dollarga teng). Steubenville & Indiana-ga Pensi 500 ming dollarlik obligatsiyalar kafolati shaklida yordam berdi. 1856 yilda Cumberland Valley temir yo'lida nazorat paketi sotib olingan va Pensilvaniya Filadelfiyada qo'shimcha liniyalar qurgan. 1857 yilda yuqorida aytib o'tilgan jamoat ishlarining asosiy yo'nalishi 7 500 000 dollarga (2019 yilda 206 million dollar) sotib olindi.[4]

Empire transport kompaniyasi

Empire Transport kompaniyasi 1865 yilda Jozef D. Potts tomonidan tashkil etilgan va Pensilvaniya temir yo'lining multimodal yuk tashish sho'ba korxonasiga aylangan. U neft tashuvchi avtoulovlarga egalik qilgan va ulardan neftni asosan mustaqil neftni qayta ishlash korxonalari uchun qayta ishlangan neftni tashishda foydalangan Jon D. Rokfeller va 1870-yillarda Standard Oil kompaniyasining neftni qayta ishlash zavodi birlashdi. Shuningdek, kompaniya yirik ko'llarda va neft quvurlarida donli yuk tashuvchi kemalarga egalik qilgan Pensilvaniyaning neft mintaqalari. 1877 yilda kompaniya ba'zi bir neftni qayta ishlash zavodlarini sotib olishga va qurishga harakat qilganda, Standard Oil kompaniyani sotib oldi.[9][10]

Penn Central birlashishi, Conrail va bugun

1960-yillarning boshlarida PRRning nazorat qiluvchi, institutsional bo'lmagan aktsiyadorlari bo'lgan Genri Striker Teylor, kimning bir qismi bo'lgan Jeykob Bunn Illinoysning biznes-sulolasi va Xovard Butcher III, Filadelfiyadagi brokerlar uyining rahbari Butcher & Sherrerd (keyinchalik Butcher & Singer).

1968 yil 1 fevralda Pensilvaniya temir yo'llari azaliy raqibi Nyu-York markaziy temir yo'li bilan birlashdi. Pensilvaniya temir yo'li Nyu-York markazini o'zlashtirdi va oxir-oqibat Penn Central Transport Company nomi bilan yurdi.

The Davlatlararo savdo komissiyasi (ICC) kasal bo'lishini talab qildi Nyu-York, Nyu-Xeyven va Xartford temir yo'li (NH) 1969 yilda qo'shilgan. Inflyatsiya, yomon boshqaruv, g'ayritabiiy ob-havo va hukumat tomonidan kafolatlangan 200 million dollarlik operatsion kreditning qaytarib olinishi kabi qator voqealar Penn Centralni 1970 yil 21 iyunda bankrotlikdan himoya qilishga ariza berishga majbur qildi.[5] 1971 yil may oyida yo'lovchilar bilan ishlash, shu jumladan uskunalar, hukumat tomonidan subsidiyalangan Milliy temir yo'l yo'lovchilar korporatsiyasi deb nomlangan kompaniyaga topshirildi yoki Amtrak. Bu Penn Central (va boshqa temir yo'llarni) pulni yo'qotadigan yo'lovchilarga xizmat ko'rsatishdan xalos qilish uchun ishlab chiqilgan. Penn Central temir yo'l liniyalari, shu jumladan sobiq Pensi liniyalari 1976 yilda Conrailga ko'chirildi va oxir-oqibat Amtrak bu yo'lni oldi Shimoli-sharqiy koridor va Keystone yo'lagi chiziqlar.

Conrail ikkiga bo'linib bo'lgandan keyin Norfolk janubiy temir yo'li va CSX transporti, sobiq Pensiyning qolgan treklari Norfolk janubiga yo'l oldi. Conrail bo'linib ketganidan keyin CSXga borgan Pensilvaniya temir yo'lining bir necha qismi (1) G'arbiy Ogayo va Shimoliy Indiana bo'ylab Fort Ueyn chizig'ining g'arbiy uchi, (2) Pope's Creek Second Merilendda, Vashingtondan faqat sharqda, (3) Landtov Subdivision, Amtrakning Pensiyning shimoliy-sharqiy yo'lakchasi va CSX-ning sobiq B & O bilan bog'laydigan DC shahridagi sobiq Pensi yuk liniyasi. Iskandariya kengaytmasi shimoliy uchida va sobiq Pensilvaniya orqali CSX ning janub tomonidagi RF & P bo'linmasi "Uzoq ko'prik "Potomak daryosi bo'ylab va (4) Terre Xeyt, Indiana shtatidan Sent-Luisgacha, Sent-Luis magistral liniyasining Illinoys segmenti (Terre Xeytning sharqiy qismi sobiq Nyu-York markazidir).

Pensilvaniya temir yo'li hali ham mavjud, ammo keyinchalik sug'urta kompaniyasiga o'tdi va endi nomi bilan yurdi Amerika Premier Anderrayterlari va hozirda sho''ba korxonasi sifatida xizmat qilmoqda Amerika moliyaviy guruhi.

Tomson (1808–1874) - bu Pensilvaniya temir yo'lini 1852 yildan 1874 yilda vafotigacha boshqargan, uni dunyodagi eng yirik biznes korxonasi va texnologik va boshqaruv innovatsiyalarining jahon darajasidagi modeliga aylantirgan tadbirkor. U Pennsining birinchi bosh muhandisi va uchinchi prezidenti bo'lib ishlagan.[21] Tomsonning hushyor, texnik, uslubiy va g'oyaviy bo'lmagan shaxsiyati Pensilvaniya temir yo'lida muhim ta'sir ko'rsatdi, u 19-asr o'rtalarida temir yo'lning rivojlanishining texnik pog'onasida edi, shu bilan birga Tomsonning shaxsiyatini konservatizm va uning barqaror o'sishida aks ettirdi. moliyaviy xatarlardan saqlanishda. Uning Pensilvaniya temir yo'li o'z vaqtida olti ming kilometrlik yo'l bilan dunyodagi eng katta temir yo'l edi va barqaror moliyaviy dividendlar, yuqori sifatli qurilish, uskunalarni doimiy ravishda takomillashtirish, texnologik yutuqlar (masalan, o'tin yoqilg'isini ko'mirga almashtirish kabi) va yangilik bilan mashhur edi. katta murakkab tashkilot uchun boshqaruv texnikasida.[22]

1871 yil 1-dekabrda Pensni arendani ijaraga oldi Birlashgan Nyu-Jersi temir yo'l va kanal kompaniyasi asl nusxasini o'z ichiga olgan Kamden va Amboy temir yo'li Kamden, Nyu-Jersi (Filadelfiyadan Delaver daryosi bo'ylab) Janubiy Amboy, Nyu-Jersi (Nyu-York shahridan Raritan ko'rfazi bo'ylab), shuningdek, Nyu-Yorkka juda yaqin Filadelfiyadan Nyu-Jersi shtatining Jersi Siti shahriga, Trenton orqali, Nyu-Jersi. Filadelfiyadagi trekka ulanish Pensi's orqali amalga oshirildi Birlashtiruvchi temir yo'l va birgalikda egalik qiladi Junction Railroad.[24]

Pensilnikiga tegishli Baltimor va Potomak temir yo'l yo'li Baltimor bilan 1872 yil 2-iyulda ochilgan Vashington, Kolumbiya Ushbu yo'nalish orqali uzatishni talab qildi ot mashinasi Baltimorda shahardan shimol tomon yo'nalgan boshqa yo'nalishlarga. 1873 yil 29 iyunda Baltimor va Potomak tunnel Baltimor orqali yakunlandi. Pensilvaniya temir yo'li Shimoliy Markaziy temir yo'l va Pensilvaniya shtatidagi Kolumbiya orqali noto'g'ri deb nomlangan Pensilvaniya havo yo'li xizmatini boshladi. Ushbu xizmat eski marshrutdan 54,5 milya (87,7 km) uzoqroq bo'lgan, ammo Baltimordagi transferdan qochgan. The Birlik temir yo'li yo'nalish 1873 yil 24-iyulda ochilgan. Ushbu yo'nalish Baltimordagi transferni bekor qildi. Pensi rasmiylari ham Union Railroad bilan ham shartnoma tuzdilar Filadelfiya, Uilmington va Baltimor temir yo'llari (PW&B) ushbu qatorga kirish uchun. Pensilvaniyaning Nyu-York - Vashington poezdlari ertasi kuni Pensilvaniya Air Line xizmatini tugatib, marshrutdan foydalanishni boshladi. 1880-yillarning boshlarida Pensilvaniya PW&B Railroad aksiyalarining ko'p qismini sotib oldi. Ushbu harakat Baltimor va Ogayo temir yo'llarini (B&O) qurishga majbur qildi Baltimor va Filadelfiya temir yo'llari bilan bog'langan Filadelfiyaga kirish huquqini saqlab qolish uchun O'qish temir yo'li uning raqobatdoshligi uchun Royal Blue Line Nyu-Yorkka etib borish uchun yo'lovchi poezdlari.

1885 yilda PRR Nyu-York shahridan Filadelfiya orqali Vashingtonga yo'lovchi poezdlari qatnovini cheklangan marshrut bilan boshladi. Ushbu xizmat "Kongress Limited Express" nomi bilan mashhur bo'ldi.[25] Xizmat kengayib bordi va 1920-yillarga kelib Pensi Nyu-York, Filadelfiya va Vashington o'rtasida soatiga yo'lovchi poezdlari qatnovini amalga oshirdi. 1952 yilda 18 ta zanglamaydigan po'latdan yasalgan strellinglar ishlab chiqarildi Tonggi Kongress va Peshindan keyin Kongress Nyu-York va Vashington o'rtasida, shuningdek Senator Bostondan Vashingtongacha.[26]

Nyu-York-Chikago

1869 yil 1-iyulda Pensilvaniya temir yo'li temir yo'lni ijaraga oldi Pitsburg, Fort Ueyn va Chikago temir yo'li Ilgari investor bo'lgan (PFtW & C). Ijara Pensilvaniyaga ushbu yo'nalishning shimoliy Ogayo va Indiana orqali to'g'ridan-to'g'ri yo'nalishini hamda shuningdek, rivojlanayotgan temir yo'l markaziga kirishni ta'minladi. Chikago, Illinoys. PFtW & C bo'yicha sotib olish: Eri va Pitsburg temir yo'li, Klivlend va Pitsburg temir yo'llari, Toledo, Kolumb va Ogayo daryolari temir yo'llari va Pitsburg, Yangstaun va Ashtabula temir yo'llari Pensilvaniyaga Eri ko'lidagi temir javhari qatnoviga kirish huquqini berdi.[8]

1887 yil 15-iyun kuni Pennsylvania Limited Nyu-York va Chikago o'rtasida yugurishni boshladi. Bu, shuningdek, har bir yo'lovchi vagonining oxiridagi yopiq platforma bo'lgan vestibyulning kiritilishi bo'lib, butun poezdga himoyalangan kirish imkoniyatini beradi. 1902 yilda Pennsylvania Limited bilan almashtirildi Pensilvaniya maxsus bu o'z navbatida 1912 yilda Broadway Limited Pensilvaniya temir yo'llari tomonidan boshqariladigan eng mashhur poezdga aylandi.[27][28] Ushbu poyezd Nyu-York shahridan Filadelfiya orqali Chikagoga, Garrisburg va Vashington o'rtasida qo'shimcha qism bilan harakatlangan (keyinchalik alohida Vashington-Chikago poezdi sifatida ishlagan, Ozodlik Limited).

Nyu-York-St. Lui

1890 yilda Pensilvaniya temir yo'l boshqaruvi qo'lga kiritildi Pitsburg, Sinsinnati, Chikago va Sent-Luis temir yo'llari (PCC & StL), o'zi Ogayo, Indiana va Illinoys shtatlaridagi ko'plab kichik chiziqlarning birlashtirilgan mahsuloti. Odatda Panhandle yo'nalishi, bu yo'nalish Pitsburgdan g'arbiy tomonga o'tib, Ogayo shtatidagi Bredfordgacha, u erda bo'linib, bitta chiziq Chikagoga, ikkinchisi esa Sent-Luis, Illinoys, orqali Indianapolis, Indiana. 1905 yilda sotib olish Vandaliya temir yo'li Missisipi daryosi bo'ylab Pensiyga kirish huquqini berdi Sent-Luis, Missuri.[8]

Uzunligining ko'p qismida ikki marotaba kuzatilgan ushbu yo'nalish Illinoysning janubidagi ko'mir mintaqasiga va Pensilvaniya temir yo'lining Moviy tasma nomli poyezdlariga yo'lovchi yo'nalishi sifatida xizmat qilgan. Sent-Luis, Jeffersonian, va Sent-Luis ruhi.[29]

"Past darajadagi" qatorlar

1906 yilga kelib, Pensilvaniya bir nechtasini qurdi past navli keskin darajadagi (nishabli) maydonlarni chetlab o'tish va tirbandlikka yo'l qo'ymaslik uchun yuk yo'nalishlari. Bunga quyidagilar kiradi:

  • 1871 yil: G'arbiy Pensilvaniya temir yo'li qurib bitkazildi uning chizig'i dan Blervill ga Allegheny City, Pensilvaniya va bilan bog'lanish Pitsburg, Fort Ueyn va Chikago[4]:63
  • 1874 yil: Allegheny Valley temir yo'lining past darajadagi liniyasi Driftwood Red Bank, Pensilvaniya[4]:121
  • 1877: The Port Perri filiali magistral liniyani Pensilvaniya temir yo'llari bilan bog'lash Pitsburg, Virjiniya va Charleston temir yo'li Pitsburg yaqinida
  • 1890 yil: Ogayo shtati ulanadigan temir yo'l Pensilvaniya temir yo'li tomonidan qurilgan bo'lib, Panhandle marshruti, PV va C va Port Perri filiali orqali Pitsburg atrofida past darajadagi bypassni taqdim etadi (va keyinchalik Brilliant Cutoff va Duff / Scully filiali orqali)[30]
  • 1892: Trenton filiali va Trenton-ni o'chirish Pensilvaniya shtatidagi Glen Lochdan sharqqa, Pensilvaniya shtatidagi Morrisvillgacha temir yo'l[31] (nafaqat past darajadagi yo'nalish, balki Filadelfiyaning uzoq masofali yorlig'i va aylanib o'tishi)
  • 1904: qayta tiklanishi Yangi Portage temir yo'li Gallitzin tunnelidan, sharqdan Yangi Portage Junctiongacha, keyin shimoldan Hollidaysburg filiali orqali Oltunaga qadar davom eting,[4]:287 yoki Altoonani chetlab o'tib, Peterburg filialida davom eting Peterburg[31]
  • 1904: The Brilliant Cutoff asosiy chiziq va Allegheny Valley temir yo'li o'rtasida va Conemaugh liniyasi
  • 1905 yil: Panhandl trassasi bo'ylab past darajadagi bypass orqali ta'minlovchi Scully filiali Chartiers Creek[32][33][34]
  • 1906: Filadelfiya va Thorndale filiali Thorndeyldan (Pensilvaniya, sharqdan Glen Lochgacha) [31][4-qayd]
  • 1906: Atglen va Susquehanna filiali Harrisburgdan Shimoliy Markaziy temir yo'l orqali, janubda Vago Junctionga, keyin sharqda Pensilvaniya shtatidagi Parkesburgga.[31][5-yozuvlar]

Boshqa ba'zi yo'nalishlar rejalashtirilgan, ammo tugallanmagan:

  • Pensilvaniya va Nyuark temir yo'llari 1905 yilda Morrisvill (Pensilvaniya) dan Koloniya (Nyu-Jersi) ga qadar past darajadagi liniyani qurish uchun birlashtirilgan. Hech qachon tugamagan,[35] ammo ba'zi ishlar Trenton hududida, shu jumladan Delaver daryosidagi ko'prik ustunlari bajarilgan. Koloniyaning shimoliy qismida hizalama alohida bo'ladigan edi, ammo buning o'rniga mavjud chiziqqa ikkita qo'shimcha trek qo'shildi. Ish 1916 yilda to'xtatilgan.[36]
  • Radebaugh (pastda) o'rtasida past darajali yo'nalish rejalashtirilgan Greensburg ) va Derri, Pensilvaniya.[31] Ushbu yo'nalish bo'yicha ishlar boshlandi, ammo hech qachon tugamadi.[37]
  • Past darajadagi marshrut Allegheny tog'lari Pensilvaniya shtati, Pitsburgdagi tirbandlikni chetlab o'tib, o'ylab topilgan, ammo hech qachon qurilmagan.[38] Ning mavjud segmentlaridan foydalangan bo'lar edi Shimoliy Markaziy temir yo'l, Filadelfiya va Eri temir yo'li, va Allegheny Valley Railway's Low Grade Division. Keyin yangi qurilish Qizil bankdan bankka ulangan bo'lar edi Fort Ueyn chizig'i da Enon.[39] Keyinchalik G'arbiy Allegheny temir yo'li ko'zda tutilgan yangi yo'nalishga o'xshash marshrutni bosib o'tdi,[40] va bir muncha vaqt Pensilvaniya temir yo'liga tegishli edi, bu uni rejalashtirilgan aylanib o'tish uchun sotib olganga o'xshaydi.[41][42]

Elektrlashtirish

Nyu-York terminal zonasida va tunnellarda ishlatiladigan PRR DD1 elektrovozi

20-asrning boshlarida Pensni sinab ko'rdi elektr energiyasi uning poezdlari uchun. Uning birinchi harakati Nyu-York terminal maydonida bo'lgan, u erda tunnellar va ko'mir yoqilishini cheklovchi shahar qonuni bug 'lokomotivlarini taqiqlagan. 1910 yilda temir yo'l a. Ishlay boshladi to'g'ridan-to'g'ri oqim (DC) 650 voltli tizim, uning uchinchi temir yo'llari bilan ishlaydigan Pensi lokomotivlari (va LIRR yo'lovchi vagonlari) Nyu-York shahridagi Penn Stantsiyasiga Gudzon daryosidagi tunnellar.[43]

Keyingi elektrlashtiriladigan maydon Pensilvaniya rasmiylari foydalanishga qaror qilgan Filadelfiya terminal maydoni edi havo liniyalari muddati tugagan shahar atrofidagi poyezdlarga elektr energiyasini etkazib berish Keng ko'cha stantsiyasi. Nyu-York terminal tizimidan farqli o'laroq, havo simlari 11000 voltli 25-Hertz quvvatiga ega bo'ladi o'zgaruvchan tok (AC) quvvati, bu kelajakda o'rnatish uchun standart bo'ldi. 1915 yilda Filadelfiyadan Paoliga (Pensilvaniya) yo'nalishni elektrlashtirish tugallandi.[44] Elektrlangan boshqa Filadelfiya yo'nalishlari bu edi Kashtan tepalik filiali (1918),[4]:371 Oq Marsh (1924), G'arbiy Chester (1928), asosiy yo'nalish Uilmington, Delaver,[4]:407 va 1930 yilda Schuylkill filiali Pensilvaniya shtatining Norristaun shahriga, Trenton (Nyu-Jersi) magistralining qolgan qismi bilan birga.

1928 yilda PRR prezidenti Uilyam Uolles Atterberi Nyu-York, Filadelfiya, Vashington va Xarrisburg o'rtasidagi liniyalarni elektrlashtirish rejalarini e'lon qildi. 1933 yil yanvar oyida Nyu-York va Filadelfiya / Vilmington / Paoli o'rtasida magistral xizmat orqali foydalanishga topshirildi. Filadelfiya va Vashington o'rtasida elektr poyezdining birinchi sinovi 1935 yil 28 yanvarda sodir bo'lgan. 1 fevral kuni Kongress cheklanganIkkala yo'nalishda ham Nyu-York va Vashington o'rtasida muntazam ravishda elektr energiyasi bilan ishlaydigan birinchi poezdlar bo'lgan GG1 -tip lokomotivlar.[45]:74

1934 yilda Pensilvaniya shtatidan 77 million dollar kredit oldi Yangi bitim "s Jamoat ishlarini boshqarish[46] 1928 yilda boshlangan elektrlashtirish loyihasini yakunlash. 1937 yil 27 yanvarda Paolidan Harrisburggacha bo'lgan magistral yo'lda ish boshlandi; Morrisvilldan Kolumbiya orqali Pensilvaniya shtatidagi Enola-Yardgacha past darajadagi yuk liniyasi; The Port-Yo'l filiali Merilend shtatining Perrivilidan Kolumbiyaga; Jeymsburg filiali va Amboy ikkilamchi yuk liniyasi Monmut Junctiondan Janubiy Amboygacha; Landover-South End yuk tashish liniyasi Merilend shtatining Landover shtatidan Vashingtongacha Potomak hovli Virjiniya, Iskandariyada. [6-eslatma] Bir yildan kamroq vaqt ichida, 1938 yil 15-yanvarda birinchi yo'lovchi poezdi Metropoliten, Filadelfiyadan Harrisburgga yangi elektrlashtirilgan liniya orqali foydalanishga topshirildi. 15 aprelda Harrisburg va Enola-Yard sharqidan elektrlashtirilgan yuk xizmati ochilish marosimi bo'lib o'tdi va shu bilan Pensining sharqiy dengiz qirg'og'ini elektrlashtirish dasturi yakunlandi.[47] Temir yo'l o'z yo'lidan 2,677 milya (4308 km) elektrlashtirgan, bu mamlakatning elektr bilan ishlaydigan standart temir yo'lining 41 foizini tashkil etadi. Elektrlashtirilgan yo'lning ba'zi qismlari hali ham Amtrak tomonidan Shimoliy-Sharqiy koridor va Keystone koridori tezyurar temir yo'l yo'nalishlari sifatida foydalaniladi va boshqariladi,[48] tomonidan SEPTA,[49] va tomonidan NJ tranzit.[50]

Uskunalar

Pensilvaniya temir yo'lining korporativ ramzi bu edi asosiy tosh, Pensilvaniya Hamdo'stligining shtat ramzi, ichida "PRR" harflari bir-biriga bog'langan. Ranglanganda, u kumushrang-kulrang chiziq va harflar bilan och qizil rangda edi.

Yuk vagonlari

Pensilvaniya temir yo'li birinchi 75-ni sotib oldi yuk vagonlari 1849 yilda. [4]:20 Ikki yil o'tgach, Pensi 439 yuk vagoniga egalik qildi. 1857 yilga kelib unda 1861 ta, 1866 yilda esa 9379 ta mashina bor edi.[51]:663 Yuk tashish uskunalari yangi quruvchilardan sotib olingan yoki temir yo'lning o'zi tomonidan qurilgan.[4]:433

Pensi o'z ichiga singib ketgan temir yo'llardan ko'proq mashinalar oldi. Ba'zi hollarda, xususiy avtomobillar yoki quruvchidan sotib olingan yoki temir yo'l sotib olingan. Bunday misollardan biri 1877 yilda Empire Transport tovarlari va neft avtomobillarini sotib olish edi.[51]:666

1860-yillarning o'rtalariga kelib temir yo'lda 9379 yuk vagonlari bor edi; o'n yil o'tgach, 32,718; 1880-yillarning o'rtalari, 49000 dan ortiq; 1896, 87000 dan ortiq.[51]:666

Pensi 1900 yilga kelib avtomobil haqida hisobot berish usullarini o'zgartirdi.[51]:667 Pensilvaniya temir yo'l tizimiga tegishli bo'lgan va boshqariladigan temir yo'llar endi hisobotlarga kiritildi. Shunday qilib, 1900 yilda Pensenni 180 mingdan ortiq yuk vagonlari tashkil etgan; 1910 yilga kelib 263,039. 1919 yilda yuk mashinalariga egalik qilishning eng yuqori cho'qqisiga Pensi xabar qilingan 282,729 yuk vagonlariga ega bo'lganida erishildi.[51]:668

Yuk vagonlari qurilishida po'lat 19-asrning keyingi qismida, vagonlar endi temirdan yasalgan karkas va yog'och korpuslar bilan qurilgan yoki umuman temir bo'lgan davrda boshlangan. 1934 yilga kelib, yog'ochdan yasalgan mashinalar bo'lmaguncha, Pensni doimiy ravishda o'zlarining yog'och mashinalarini po'lat versiyalar bilan almashtirdilar.[51]:669

20-asrning birinchi choragi davomida Pensilvaniya temir yo'l yuk vagonining o'rtacha sig'imi 31 tonnadan 54 tonnaga ko'tarildi. Bu 30-yillarning o'rtalarida 55 tonnagacha, keyin 1945 yilda 56 tonnagacha o'sdi.[51]:669

1946 yil boshida Pensining yuk vagonlari egaligi 240 293 vagonga kamaydi[51]:663 1963 yilda esa 140,535 ga tushdi.

Pensilvaniya temir yo'llari yuk vagonlari uchun tasniflash tizimidan foydalangan. Pensi o'zlarining lokomotivlariga o'xshab, yuk va texnik xizmat ko'rsatadigan vagonlarning har xil va pastki turlarini belgilashda harflar tizimidan foydalangan.[52]

Bo'yoq sxemalari

Ta'kidlanganidek, pensiya ranglari va bo'yoq sxemalari standartlashtirilgan. Lokomotivlar yashil rangga bo'yalgan, shuning uchun u deyarli qora bo'lib tuyulardi. Ushbu rangning rasmiy nomi DGLE (quyuq yashil lokomotiv emal) edi, garchi ko'pincha "Brunsvik Yashil" deb nomlansa ham. Lokomotivlarning yurishi qora rangga bo'yalgan bo'lib, "Haqiqiy qora" deb nomlangan. The yo'lovchi avtoulovlari Pensni bo'yalgan Toskana qizil, g'isht rangidagi qizil soya. Ba'zi elektrovozlar va yo'lovchilar tashiydigan aksariyat teplovozlar ham Toskana Qizil rangiga bo'yalgan. Pensilvaniyaning yuk mashinalari temir rang-oksidli soya rangiga ega bo'lgan "Freight Car Color" deb nomlanuvchi o'ziga xos rangga ega edi. Yo'lovchi lokomotivlari va avtoulovlarda yozuvlar va chizmalar dastlab asl oltin bargda qilingan. Ikkinchi Jahon urushidan so'ng, yozuvlar Buff Yellow deb nomlangan sariq rangning engil soyasida qilingan.[53]

Pensilvaniya temir yo'li o'zining mavjud bo'lgan davrining aksariyat qismida lokomotiv tanlashda konservativ bo'lib, lokomotiv turlarida ham, ularning tarkibiy qismlarida ham standartlashtirishni amalga oshirdi.[54] AQSh temir yo'llari orasida deyarli yakka o'zi, Pensi bug 'lokomotiv sinflarining ko'pini o'zi ishlab chiqardi. Ularning aksariyati qurilgan Altoona ishlaydi, Pensi inshootlari temir yo'l ehtiyojlarini qondira olmagandagina autsorsing. Bunday hollarda, PRR loyihalarini qurish uchun subpudratchilar yollandi,[55] Ko'pgina temir yo'llardan farqli o'laroq, keng spetsifikatsiyalarga buyurtma bergan va ko'pgina dizayn tanlovlarini quruvchiga topshirgan.[54]

Pensilvaning sevimli, autsorsingli lokomotiv ishlab chiqaruvchisi edi Bolduin lokomotiv zavodi, xom ashyo oldi va tayyor mahsulotni Pensi liniyalarida jo'natdi. Ikki kompaniyaning bosh qarorgohi bir shaharda joylashgan; Pensni va Bolduin rahbariyati va muhandislari bir-birini yaxshi bilishardi. Pensi va Bolduin do'konlari ishlay boshlaganda, buyurtmalar shu tomonga ketardi Lima lokomotiv zavodi Ogayo shtatining Lima shahrida.[55] Faqatgina so'nggi chora sifatida Pensni bundan foydalanishi mumkin edi Amerika Lokomotiv kompaniyasi (Alco), Nyu-York shtatidagi Schenectady-da joylashgan bo'lib, u Pensining raqibi Nyu-York Markaziy uchun ham qurilgan.

Pensilvaniya temir yo'li o'zining lokomotivlarida yoqadigan dizayn uslubiga ega edi. Bir misol to'rtburchak elkali edi Belpaire yong'in qutisi. Ushbu ingliz uslubidagi yong'in qutisi AQShning boshqa lokomotiv ishlab chiqaruvchilari kamdan kam foydalanadigan Pensni savdo belgisi edi. Pensi ham ishlatilgan trekka harakatlanayotganda lokomotiv uchun suv olish uchun keng qamrovli. Ushbu tizimdan foydalanish degani tenderlar ularning lokomotivlari ko'mirning suvga nisbatan ancha katta qismiga ega edi (uni ishlatish paytida bortga olib bo'lmaydi). Pensilvaniya lokomotivlari ularga toza ko'rinishga ega edi. Faqatgina kerakli qurilmalardan foydalanilgan va ular lokomotivga chiroyli tarzda o'rnatilgandi.[54] Tutun qutilarining old tomonlarida yuk teplovozini bildiruvchi dumaloq lokomotiv raqamli taxtasi yoki yo'lovchi lokomotivini bildiruvchi asosiy tosh raqamli taxtasi bor edi. Aks holda tutun qutisi tartibsiz edi, faqat yuqori qismida chiroq va orqasida bug 'bilan ishlaydigan turbo generator. Keyingi yillarda ikkalasining pozitsiyasi o'zgarib ketdi, chunki generator lampaga qaraganda ko'proq texnik xizmatga muhtoj.[54]

Parovozning har bir sinfiga sinf nomi berilgan.[56] Dastlab bu oddiygina xat edi, ammo qisqa vaqt ichida sxema o'zgartirildi, shunda ularning har biri g'ildirak tartibga solish o'z harfiga ega edi va bir xil tartibdagi har xil turdagi harfga har xil raqamlar qo'shilgan edi. Kichik harflar kichik harf bilan ko'rsatilgan; 20-asrning 20-yillari o'rtalariga qadar super isitish "s" lar tomonidan belgilanardi, shu vaqtgacha barcha yangi lokomotivlar o'ta qizib ketgan. K4sa sinf a 4-6-2 Pensi tomonidan ishlab chiqilgan to'rtinchi Tinch okeanining "Tinch okeani" turi (K). U o'ta qizdirilgan (lar) va asl nusxadan keyingi birinchi variant (a) bo'lgan (o'qilmagan). Buxoriy lokomotivlar 1957 yilgacha Pensi parkining tarkibida bo'lib kelgan.

The Pennsy's reliance on steam locomotives in the mid-20th century contributed to its decline. Steam locomotives require more maintenance than diesel locomotives, are less cost efficient, and require more personnel to operate. Like other railroads, the Pennsy was unable to update its roster at will during the World War II years; by the end of the war their roster was in rough shape. In addition, the Pennsy was saddled with unsuccessful experimental steam locomotives such as the 1-savol, S1 va T1 "Ikki tomonlama disk " locomotives, and the S2 turbine locomotive. Unlike most of their competition, the Pennsy did not acquire any Northerns or Berkshires.

Pennsy competitors managed this period better with their diesel locomotive rosters.[57] The Pennsylvania Railroad voluntarily preserved a roundhouse full of representative steam locomotives at Northumberland, Pensilvaniya, in 1957 and kept them there for several decades. These locomotives, with the exception of I1sa #4483 which is on display at Hamburg, New York, are now at the Pensilvaniya temir yo'l muzeyi in Strasburg, Pennsylvania. In sharp contrast, the New York Central's Alfred E. Perlman deliberately scrapped all but two[7-yozuvlar] large, steam locomotives, and these survived only by accident.

On December 18, 1987, the State of Pennsylvania designated the Pennsy's K4lar as the official State Steam Locomotive. The two surviving K4s are № 1361, which is undergoing restoration to operating condition at the Temiryo'lchilar yodgorlik muzeyi yilda Oltona va № 3750, which remains on static display at the Pennsylvania Railroad Museum yilda Strasburg.[58]

2020 yildan boshlab the only operable Pennsylvania Railroad steam locomotive is class B4a engine # 643, built in July 1901 in Altoona. Engine 643 is maintained by volunteers of the Williams Grove Historical Steam Engine Association outside of Harrisburg, and is operated several weekends each summer.[59] 2020 yildan boshlab however, a major construction project has been underway since 2014, building a new operational example of a class T1 engine numbered 5550, as all original class T1 locomotives have been scrapped. The project is being undertaken by the Pennsylvania Railroad T1 Steam Locomotive Trust and is projected to be finished by 2030.[60]

When work on the Hudson River tunnels and New York's Penn Station was in progress, the type of elektrovozlar to be used was an important consideration. At that time only a few electric locomotives existed. Several experimental locomotives were designed by railroad and Vestingxaus engineers and tried on the West Jersey & Seashore Railroad trek From these tests the DD1 class was developed.[43] The DD1s were used in pairs (back-to-back). Thirty-three of these engines having Westinghouse equipment were built at Altoona. They were capable of speeds up to 85 miles per hour (137 km/h). Placed in service in 1910, they performed well, lasting in regular service through the 1940s.[45]:74–75

Steel suburban passenger cars capable of being electrified for MU operation were designed due to the need for such cars in service to Penn Station through its associated tunnels and were designated MP54.[61] Designs for corresponding cars accommodating baggage and mail were produced also. Eight of these cars were electrified with DC equipment to provide shuttle service from Penn Station to Manhattan Transfer between 1910 and 1922. More extensive electrification plans required AC electrification, starting with 93 cars for the Paoli Line in 1915. With the expansion of the AC electrification, additional MP54 cars were electrified or purchased new until a total of 481 cars was reached in 1951. Replacement with newer types of cars began in 1958 and the last MP54 cars were retired in the early 1980s.[62]

Yagona FF1 appeared in 1917 and ran experimentally for a number of years in preparation for electrification over the Allegheny Mountains that never came to fruition. Its AC induction motors and side-rod drive powered six axles.[43] It developed a starting tractive force of 140,000 pounds, which was capable of ripping couplers out of the fragile wooden freight cars in use at the time.[63]:123

In 1924 another side-rod locomotive was designed: (the L5 sinf).[43] Two DC locomotives were built for the New York electrified zone and a third, road number 3930, was AC-equipped and put in service at Philadelphia. Later 21 more L-5 locomotives were built for the New York service. A six-wheeled switching engine was the next electric motive power designed, being classified as B1.[43] Of the first 16 AC engines, two were used at Philadelphia and 14 on the Bay Ridge line, while 12 DC-equipped engines were assigned to Sunnyside hovli Nyu-Yorkning Kvins shahrida.

The O1 class was a light passenger type.[43] Eight of these engines were built from June 1930 to December 1931. The P5 class was also introduced, with two of this class being placed in service during July and August 1931.[64] Following these came the P5A, a slightly heavier design capable of traveling 80 miles per hour (130 km/h) and with a tractive force of 56,250 pounds. In all, 89 of these locomotives were built. The first had a box cab design and were placed in service in 1932. The following year, the last 28 under construction were redesigned to have a streamlined type of cab. Some engines underwent re-gearing for freight service.[45]:74–75

In 1933 two entirely new locomotives were being planned: the R1 and the GG1 class. The R-1 had a rigid frame for its four driving axles, while the GG-1 had two frames which were articulated. Both of these prototypes, along with an O-1, a P5A and a K4s steam locomotive underwent exhaustive testing. Testing was conducted over a special section of test track near Claymont, Delaware, and lasted for nearly two years.[64]

As a result of these experiments, the GG1 type was chosen and the construction of 57 locomotives was authorized. The first GG1 was finished in April and by August 1935 all 57 were completed. These first GG1 engines were designated for passenger service, while most of the P5A type were made available for freight service. Some of the later-built GG1s were assigned to freight service as well. The total number of GG1s built was 139. They are rated at 4,620 hp at speeds of 100 miles per hour (160 km/h).[45]:75

On August 26, 1999, the U.S. Postal Service issued commemorative 33-cent Hammasi bortda! 20th Century American Trains markalar. These commemorative stamps featured five celebrated American passenger trains from the 1930s and 1940s. One of the five stamps features an image of a GG-1 locomotive pulling the "Congressional Limited Express." The official Pennsylvania State Electric Locomotive is the GG-1 #4859. It received this designation on December 18, 1987, and is currently on display in Harrisburg, Pennsylvania.[58]

In June 1937, the Pennsy acquired its first teplovoz: a 600-hp diesel-electric dvigatelni almashtirish from Electro-Motive Corporation (EMC), a predecessor of General Motors Elektr-Motiv bo'limi (EMD). EMC called it an SW model; the railroad dubbed it class ES6.[65]

The Pennsy bought its second diesel, another switcher, in October 1941: an EMD NW2 (Pennsy class ES10). Wartime restrictions soon restricted locomotive builders' production of diesels intended for freight service. Still, the Pennsy managed to add 15 Baldwin switchers and one EMD switcher.

After the war, the Pennsy began to buy diesel locomotives in earnest. From 1945 through 1947, the railroad bought roughly 100 switcher, freight, and passenger diesels from various builders, then another 800 or so (total) in 1948 and 1949.[65]

Passenger Units

For passenger units, the PRR purchased 60 E7 -class locomotives from EMD, which the Pennsy dubbed the EP20 class. 46 of this number were designated "A" units, meaning that they had a cab for the train crew. The remaining 14 were "B" units, cabless booster units controlled by an "A" unit. The Pennsy also acquired 15 Alco PA1/PB1 units (class AFP20) and 27 Baldwin DR-6-4-2000 (class BP20) units.[65] The Baldwin units were originally for the passenger service fleet, but these locomotive proved troublesome and some were reclassified as BF16z freight locomotives.[66]

The Pennsy also bought 24 Baldwin DR-12-8-1500/2s, called "Centipedes" and classified by Pennsy as BP60. The Centipede had an immense weight of 593.71 short tons (538,600 kg) and a starting tractive effort of 205,000 pounds. Unreliable and expensive to maintain, they were quickly relegated to helper service.[67]

From 1950 to 1952, the Pennsy bought 74 EMD E8A locomotives, the successor to the E7, and classified them EP22s. Also, the PRR purchased 40 dual-service EMD FP7A units which were similar to the E7/8 units, but using 4 axles instead of 6.

Freight Units

From the late 1940s through to the merger with the New York Central in 1968, the Pennsy purchased about 1,500 diesel freight units.[65][8-yozuv] 2/3 of these units were built by EMD, primarily F3s, F7s, GP9lar, GP35s, SD40s va SD45s. Early on in dieselization of freight units, the Pennsy purchased cab units from Alco, Baldwin, EMD, and Fairbanks Morse. Heading into the 1950s, the Pennsy continued to add more diesel units to their fleet. Still preferring EMD, the Pennsy did add FA birliklari va Baldwin RF-16 "Sharks". In 1956, the Pennsy called for bids to supply a large order of diesel locomotives. GM/EMD gave the Pennsy an exceptional deal on new, reliable GP9s, and received the entire order. When this large diesel order arrived the following year, the Pennsy retired all of its remaining steam engines. One of the losing bidders, Baldwin Locomotive Works — a longtime supplier of Pennsy locomotives — had been counting on winning at least some of the work. When EMD won it all, the 126-year-old Baldwin declared bankruptcy.[68]

For the last decade of Pennsy's existence (1960s), the Pennsy was ordering 4-axle power, buying Alco's 'Asr ' series locomotives, newcomer General Electric (GE) U25Bs, and EMD GP30s and GP35s. But by 1965, the Pennsy turned exclusively to 6-axle power, buying Alco's C628 va C630, GE's U25C, U28C va U30C, and EMD's SD35, SD40, and SD45.[65]

Signal

Photo of position light signals on signal bridge
Position light signals

The Pennsylvania Railroad was one of the first railroads to replace semafor signallari bilan position-light signals.[56] Such signals, which featured a large round target with up to eight amber-colored lights in a circle and one in the center, could be lit in various patterns to convey different meanings, were more visible in fog, and remained effective even when one light in a row was inoperative.[69]

Signal aspects, or meanings, were displayed as rows of three lit lights. The aspects corresponded with upper-quadrant semaphore signal positions: vertical for "proceed", a 45° angle rising to the right for "approach", horizontal for "stop", a 45° angle rising to the left for "restriction", a "X" shape for "take siding", and a full circle (used in electrified territory) for "lower pantograph". Additional aspects were conveyed with a second target head below the first, either a single light, a partial target, or a full target. Separate Manual Block signal aspects existed as well.[69]

In later years, interlocking home signals north and west of Rockville (near Harrisburg) were modified so that the two outside lights in the horizontal "stop" row had red lenses; the center lamp would be extinguished when the signal displayed "stop".[69] Such "red-eye" lenses were also temporarily installed at Overbrook Interlocking near Philadelphia.[69]

Starting in the late 1920s, the Pennsy installed Pulse code cab signaling along certain tracks used by high-speed passenger trains. Information traveled through the rails using track circuits, was picked up by a sensor on the locomotive, and displayed in the engineer's cab. The Pennsy ultimately installed cab signals on its New York-Washington, Philadelphia-Pittsburgh, and Pittsburgh-Indianapolis lines (the latter which was later downgraded by PC and ultimately abandoned by Conrail). The Pennsylvania also experimented with cab signals without wayside signals, an approach later expanded by Conrail (Conemaugh line ) and Norfolk Southern Railway (Cleveland line ). Cab signals were subsequently adopted by several other U.S. railroads, especially on passenger lines. This technology, advanced for its time, is still used by Amtrak.[69]

The main shops of the Pennsylvania Railroad were located at Altoona. Additional repair facilities were located in Harrisburg, Pittsburgh, and Mifflin. Fort Wayne, Indiana, also became a key shop for the railroad.

Juniata Shops, part of the PRR Altoona Works

In 1849, Pennsy officials developed plans to construct a repair facility at Altoona. Construction started in 1850, and soon, several small buildings housed a mexanika sexi, woodworking shop, blacksmith shop, locomotive repair shop, and foundry. These facilities were later demolished to make room for continuing expansion.

By 1926, the Altoona Works occupied 217.82 acres (88.15 ha) and consisted of four units: the Altoona Machine Shops, Altoona Car Shops, Juniata Shops, and South Altoona Foundries.[4]:432–436

  • The Altoona Machine Shops consisted of over a dozen buildings and performed locomotive repairs, plus made locomotive repair parts and non-metal castings.
  • The Altoona Car Shops were built beginning in 1869. By 1926, it included a dozen buildings, built passenger and freight cars, and repaired same.
  • The Juniata Shops were built out of need for more shop space at Altoona, in 1889. These shops consisted of 10 buildings, and constructed locomotives and performed heavy repairs of locomotives.
  • The South Altoona Foundries were built, again, out of need for more space at Altoona, in 1904. The shops primarily made kulrang temir castings.

In 1875, the Altoona Works started a Test Department for Pennsy equipment, both built and purchased.[4]:435 In following years, the Pennsylvania Railroad led the nation in the development of research and testing procedures of practical value for the railroad industry. Use of the testing facilities was discontinued in 1968.[5]:1-bob

The Pennsylvania Railroad had several temir yo'l bog'lari (rail yards) throughout its system.

  • Konvey-Yard was built in the 1880s, 22 miles (35 km) northwest of Pittsburgh in Conway, Pennsylvania. Conway was built strategically in the middle of the Pennsylvania's system and started as a poling yard. The yard was made into a hump yard in 1901 to increase the volume of cars handled.[70] By 1957, it was the world's largest automatic classification yard.[71]
  • Crestline Yard was built by the Pittsburgh, Fort Wayne & Chicago Railway around 1863 and significantly improved in the early 1920s by the Pennsy to speed Chicago shipments and eliminate east and westbound freight classification at Fort Wayne.[72] Crestline is located about halfway between Pittsburgh and Chicago in Crestline, Ohio, and could hold over 1,600 cars.[73]
  • Enola Yard was built in the early 1900s and lies across the Susquehanna River from Harrisburg. The yard grew from humble beginnings of 12 tracks to over 140 miles (230 km) of tracks, capable of handling thousands of freight cars and becoming the world's largest freight rail yard by the 1940s.[45]:58
  • Sunnyside hovli was completed in 1910 for use with Penn Station in New York City. The yard is across the East River from Penn Station in Manhattan, situated in Sunnyside, Long Island. Sunnyside yard was capable of storing over 1,000 passenger cars, occupying a roughly rectangular area 8,815 feet (2,687 m) long by 1,625 feet (495 m) wide; 192 acres (78 ha) in all.[74]

The Pennsy built several grand passenger stations, alone or with other railroads. These architectural marvels, whose city name was usually preceded by "Penn Station", were the hubs for the PRR's passenger service. Many are still in use today, served by Amtrak and regional passenger carriers.

The asl Pensilvaniya stantsiyasi was designed by the noted architectural firm of McKim, Mead and White and was modeled on the Roman Caracalla hammomlari; it was notable for its high vaulted ceilings. The station opened in 1910 to provide access to Manhattan from New Jersey without having to use a ferry, making the Pennsy the only railroad to enter New York City from the south. The station was served by the Pennsy's own trains as well as those of its subsidiary, the Long Island temir yo'l yo'li. Infamously, the station's headhouse was demolished for redevelopment in 1963. However, most of the station's rail infrastructure (platforms, tracks, concourses, waiting room) and staircases were below street level, and survived as the current Pennsylvania Station. The station continues as an underground operation (serving Amtrak, New Jersey Transit and the LIRR) and is the busiest intercity railroad station in the United States.[75]

Newark's Pennsylvania Station was designed by McKim, Mead and White. It opened in 1935, was completed in 1937 and was refurbished in 2007.[76] Its style is a mixture of Art Deco va Neo-klassik. All Amtrak trains stop here, and the station serves three commuter lines, Yo'l rapid transit to Jersey City and Manhattan, and the Newark yengil temir yo'li.

Broad Street Station was the first of the great passenger stations built by the Pennsy. Opened in 1881 at a cost of $4,272,268.53 ($113 million in 2019),[4] the station was expanded in the early 1890s by famed Philadelphia architect Frank Furness. For most of its existence it was, with City Hall, one of the crown jewels of Philadelphia's architecture, and until a 1923 fire, had the largest train shed in the world (a 91 m span). It was the terminal for the Pennsylvania in Philadelphia, bringing trains into the center of the city at Broad and Filbert streets. The station was demolished in 1953 after the Pennsy moved passenger service to 30-ko'cha bekati.

30th Street Station displays its majestic—and traditional—architectural style with its enormous waiting room and its vestibules. The station, in spite of its architectural classicism, opened in 1933, when modern and Art Deco styles were more popular. Its construction was needed to accommodate increased intercity and suburban traffic. It replaced the 32nd Street Station (West Philadelphia). It is now the primary rail station in Philadelphia, serving long-distance and commuter trains.

The original station was built in 1865 and was destroyed by fire in 1877 during the Pittsburgh Riots. A temporary station was quickly built but, remained in service until the early 1900s, when the present station was built between 1898–1903, renovated in 1954, and partially repurposed in 1988.[77] The station was originally called "Union Station" as the terminal for the Allegheny Valley, PFtW&C, and the Pennsylvania Railroad.
