Transcontinental railroad

Transcontinental railroads in and near the United States by 1887.

A transcontinental railroad or transcontinental railway is contiguous railroad trackage that crosses a continental land mass and has terminals at different oceans or continental borders. Such networks can be via the tracks of either a single railroad or over those owned or controlled by multiple railway companies along a continuous route. Although Europe is crisscrossed by railways, the railroads within Europe are usually not considered transcontinental, with the possible exception of the historic Orient Express. Transcontinental railroads helped open up unpopulated interior regions of continents to exploration and settlement that would not otherwise have been feasible. In many cases they also formed the backbones of cross-country passenger and freight transportation networks. Many of them continue to have an important role in freight transportation and some like the Transsiberian Railroad even have passenger trains going from one end to the other.

A transcontinental railroad in the United States is any continuous rail line connecting a location on the U.S. Pacific coast with one or more of the railroads of the nation's eastern trunk line rail systems operating between the Missouri or Mississippi Rivers and the U.S. Atlantic coast. The first concrete plan for a transcontinental railroad in the United States was presented to Congress by Asa Whitney in 1845.

A series of transcontinental railroads built over the last third of the 19th century created a nationwide transportation network that united the country by rail. The first of these, the 3,103 km (1,928 mi) "Pacific Railroad", was built by the Central Pacific Railroad and Union Pacific Railroad to link the San Francisco Bay at Alameda, California, with the nation's existing eastern railroad network at Council Bluffs, Iowa/Omaha, Nebraska, thereby creating the world's first transcontinental railroad when it opened in 1869. Its construction was made possible by the US government under Pacific Railroad Acts of 1862, 1864, and 1867.

Transcontinental railroad

The U.S.'s First Transcontinental Railroad was built between 1863 and 1869 to join the eastern and western halves of the United States. Begun just before the American Civil War, its construction was considered to be one of the greatest American technological feats of the 19th century. Known as the "Pacific Railroad" when it opened, this served as a vital link for trade, commerce, and travel and opened up vast regions of the North American heartland for settlement. Shipping and commerce could thrive away from navigable watercourses for the first time since the beginning of the nation. Much of this route, especially on the Sierra grade west of Reno, Nevada, is currently used by Amtrak's California Zephyr, although many parts have been rerouted.

The transcontinental railroad provided fast, safe, and cheap travel. The fare for a one-week trip from Omaha to San Francisco on an emigrant sleeping car was about $65 for an adult. It replaced most of the far slower and more hazardous stagecoach lines and wagon trains. The number of emigrants taking the Oregon and California Trails declined dramatically. The sale of the railroad land grant lands and the transport provided for timber and crops led to the rapid settling of the "Great American Desert".

The Union Pacific recruited laborers from Army veterans and Irish immigrants, while most of the engineers were ex-Army men who had learned their trade keeping the trains running during the American Civil War.

The Central Pacific Railroad faced a labor shortage in the more sparsely settled West. It recruited Cantonese laborers in China, who built the line over and through the Sierra Nevada mountains and then across Nevada to their meeting in northern Utah.

Subsequent transcontinental routes

The Gould System

George J. Gould attempted to assemble a truly transcontinental system in the 1900s. The line from San Francisco, California, to Toledo, Ohio, was completed in 1909, consisting of the Western Pacific Railway, Denver and Rio Grande Railroad, Missouri Pacific Railroad, and Wabash Railroad. Beyond Toledo, the planned route would have used the Wheeling and Lake Erie Railroad (1900), Wabash Pittsburgh Terminal Railway, Little Kanawha Railroad, West Virginia Central and Pittsburgh Railway, Western Maryland Railroad, and Philadelphia and Western Railway, but the Panic of 1907 strangled the plans before the Little Kanawha section in West Virginia could be finished. The Alphabet Route was completed in 1931, providing the portion of this line east of the Mississippi River. With the merging of the railroads, only the Union Pacific Railroad and the BNSF Railway remain to carry the entire route.


Lord Strathcona driving the "Last Spike" of Canada's first transcontinental railroad, the Canadian Pacific Railway, in 1885

The completion of Canada's first transcontinental railway with the driving of the Last Spike at Craigellachie, British Columbia, on November 7, 1885, is an important milestone in Canadian history. Between 1881 and 1885, the Canadian Pacific Railway (CPR) completed a line that spanned from the port of Montreal to the Pacific coast, fulfilling a condition of British Columbia's 1871 entry into the Canadian Confederation. The City of Vancouver, incorporated in 1886, was designated the western terminus of the line. The CPR became the first transcontinental railway company in North America in 1889 after its International Railway of Maine opened, connecting CPR to the Atlantic coast.

The construction of a transcontinental railway strengthened the connection of British Columbia and the Northwest Territories to Canada they had recently joined, and acted as a bulwark against potential incursions by the United States.

Subsequently, two other transcontinental lines were built in Canada: the Canadian Northern Railway (CNoR) opened another line to the Pacific in 1912, and the combined Grand Trunk Pacific Railway (GTPR)/National Transcontinental Railway (NTR) system opened in 1917 following the completion of the Quebec Bridge, although its line to the Pacific opened in 1914. The CNoR, GTPR, and NTR were nationalized to form the Canadian National Railway, which currently is now Canada's largest transcontinental railway, with lines running all the way from the Pacific Coast to the Atlantic Coast.

Central America (inter-oceanic lines)

Panama (South America)

Current Panama Canal Railway line (interactive version)

The first railroad to directly connect two oceans (although not by crossing a broad "continental" land mass) was the Panama Rail Road. Opened in 1855, this 77 km (48 mi) line was designated instead as an "inter-oceanic" railroad crossing Country at its narrowest point, the Isthmus of Panama, when that area was still part of Colombia. (Panama split off from Colombia in 1903 and became the independent Republic of Panama). By spanning the isthmus, the line thus became the first railroad to completely cross any part of the Americas and physically connect ports on the Atlantic and Pacific Oceans. Given the tropical rain forest environment, the terrain, and diseases such as malaria and cholera, its completion was a considerable engineering challenge. The construction took five years after ground was first broken for the line in May, 1850, cost eight million dollars, and required more than seven thousand workers drawn from "every quarter of the globe."

This railway was built to provide a shorter and more secure path between the United States' East and West Coasts. This need was mainly triggered by the California Gold Rush. Over the years the railway played a key role in the construction and the subsequent operation of the Panama Canal, due to its proximity to the canal. Currently, the railway operates under the private administration of the Panama Canal Railroad Company, and its upgraded capacity complements the cargo traffic through the Panama Canal.


Guatemala railway (defunct) (interactive version)

A second Central American inter-oceanic railroad began operation in 1908 as a connection between Puerto San José and Puerto Barrios in Guatemala, but ceased passenger service to Puerto San José in 1989.

Costa Rica

A third Central American inter-oceanic railroad began operation in 1910 as a connection between Puntarenas and Limón in 1,067 mm (3 ft 6 in) gauge. It currently (2019) sees no passenger service.

South America

There is activity to revive the connection between Valparaíso and Santiago in Chile and Mendoza, Argentina, through the Transandino project. Mendoza has an active connection to Buenos Aires. The old Transandino began in 1910 and ceased passenger service in 1978 and freight 4 years later. Technically a complete transcontinental link exists from Arica, Chile, to La Paz, Bolivia, to Buenos Aires, but this trans-Andean crossing is for freight only.

On December 6, 2017 the Brazilian President Michel Temer and his Bolivian counterpart Morales signed an agreement for an Atlantic - Pacific railway. The construction will start in 2019 and will be finished in 2024. The new railway is planned to be 3750 km in length. There are two possible tracks in discussion: Both have an Atlantic end in Santos, Brazil but the Pacific ends are in Ilo, Peru and Matarani, Peru.

Another longer Transcontinental freight-only railroad linking Lima, Peru, to Rio de Janeiro, Brazil is under development.



  • The Trans-Asian Railway is a project to link Singapore to Istanbul and is to a large degree complete with missing pieces primarily in Myanmar. The project has also linking corridors to China, the central Asian states, and Russia. This transcontinental line unfortunately uses a number of different gauges, 1,435 mm (4 ft 8 12 in), 1,676 mm (5 ft 6 in), 1,520 mm (4 ft 11 2732 in) and 1,000 mm (3 ft 3 38 in), though this problem may be lessened with the use of variable gauge axle systems such as the SUW 2000.
  • The TransKazakhstan Trunk Railways project by Kazakhstan Temir Zholy will connect China and Europe with standard gauge 1,435 mm (4 ft 8 12 in). Construction is set to start in 2006. Initially the line will go to western Kazakhstan, south through Turkmenistan to Iran, then to Turkey and Europe. A shorter to-be-constructed 1,435 mm (4 ft 8 12 in) link from Kazakhstan is considered going through Russia and either Belarus or Ukraine.
  • The Baghdad Railway connects Istanbul with Baghdad and finally Basra, a sea port at the Persian Gulf. When its construction started in the 1880s it was in those times a Transcontinental Railroad.[clarification needed]




  • The north–south transcontinental rail corridor opened in 2004, when a final, 2248 km (1397 mi), line between Tacoola and Darwin was completed. The length of the corridor is 2975 km (1849 mi). Following 126 years of freight and passengers alike having to be transferred between trains on tracks of different gauges, the corridor is now entirely 1435 mm (4 ft 8​12 in) standard gauge. It is an important line for freight. An upmarket tourist passenger train, The Ghan, makes the journey once a week in each direction, but there is no intermediate passenger traffic.
  • In 2006, proposals for new lines in Queensland that would carry both intrastate coal traffic and interstate freight traffic envisaged standard gauge lines penetrating the state in considerable stretches for the first time.
  • A standard gauge Inland Railway, under construction as of 2020, is planned to extend from Melbourne to Cairns.



  • There are several ways to cross Africa transcontinentally via connecting east–west railways. One is the Benguela railway, completed in 1929. It starts in Lobito, Angola and connects through Katanga to the Zambia railways system. From Zambia several ports are accessible on the Indian Ocean: Dar es Salaam in Tanzania through the TAZARA, and, through Zimbabwe, Beira and Maputo in Mozambique. The Angolan Civil War has made the Benguela line largely inoperative, but efforts are being taken to restore it. Another west–east corridor leads from the Atlantic harbours in Namibia, either Walvis Bay or Luderitz to the South African rail system that, in turn, links to ports on the Indian Ocean ( i.e. Durban, Maputo).
  • A 1015 km gap in the east–west line between Kinshasa and Ilebo filled by riverboats could be plugged with a new railway.
  • There are two proposals for a line from the Red Sea to the Gulf of Guinea, including TransAfricaRail.
  • In 2010 a proposal sought to link Dakar to Port Sudan. Thirteen countries would be on the main route; another six would be served by branches.


  • A north-south transcontinental railway had been proposed by Cecil Rhodes, who termed it the Cape-Cairo railway. This system would act as a direct route from the northernmost British possession in Africa, Egypt, to the southernmost one, the Cape Colony. The project was never completed. During its development, a competing French colonial project for a competing line from Algiers or Dakar to Abidjan was abandoned after the Fashoda incident. This line would have had four gauge islands in three gauges.
  • An extension of Namibian Railways is being built in 2006 with the possible connection to Angolan Railways.
  • Libya has proposed a Trans-Saharan Railway connecting possibly to Nigeria which would connect with the proposed AfricaRail network.
