Transcontinental Railroad

American First Transcontinental Railroad (1869-)

The Transcontinental Railroad is the popular name of the U.S. railroad line (known at the time as the "Pacific Railroad") completed in 1869.

By linking with the existing railway network of the Eastern United States, the road thus connected the Atlantic and Pacific coasts by rail for the first time. Opened for through traffic on May 10, 1869, with the driving of the "Last Spike" at Promontory Summit, Utah, the road established a transcontinental mechanized transportation network that revolutionized the population and economy of the American West.
