The two railroad companies involved in the transcontinental  railroad were the Union Pacific and the Central Pacific. They  completed the track on May 10, 1869 at Promontoryâ¦ Summit, Utah.
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 the Wabash Railroad. One motive for the Gadsden Purchase of land from Mexico in 1853 was to obtain suitable terrain for a southern transcontinental railroad, as the southern portion of the Mexican Cession was too mountainous. 2  The Southern Pacific Railroad was completed in 1881.
