The two companies that accepted the government's challenge to build the transcontinental railroad line were the Central Pacific Railroad and the Union Pacific Railroad. The Central Pacific started in California and worked eastward, while the Union Pacific began in Nebraska and moved westward. Their efforts culminated in the completion of the railroad at Promontory Summit, Utah, in 1869, which significantly enhanced transportation and commerce across the United States.
