First Transcontinental Railroad (North America)

This article refers to a railroad built in the United States between Omaha and Sacramento completed in 1869. For other transcontinental railroads see: Transcontinental railroad. The First Transcontinental Railroad in the United States was built across North America in the 1860s, linking the railway network of the Eastern United States with California on the Pacific coast. Ceremonially completed on May 10, 1869, at the famous "golden spike" event at Promontory Summit, Utah, it created a nation-wide mechanized transportation network that revolutionized the population and economy of the American West. This network caused the wagon trains of previous decades to become obsolete, exchanging it for a modern transportation system.
