Historical Issue-Analysis and Decision-Making: The Transcontinental Railroad
As early as 1830, people in the United States speculated about the possibility of a transcontinental railroad that would connect the eastern states with the Pacific coast. Around 1855, Secretary of War Jefferson Davis commissioned surveys in preparation for the building of rail lines across the continent. Several of the surveys, conducted by the War Department and the Army Corps of Topographical Engineers, are included in the collection. Search on railroad for these maps as well as other pertinent items.

In 1862, President Abraham Lincoln signed the Pacific Railway Act, authorizing two companies to construct the transcontinental railroad, called the Central Pacific Railroad. The Central Pacific Railroad Company laid tracks eastward from Sacramento, California while the Union Pacific Railroad Company laid tracks westward from Omaha, Nebraska. They met in Promontory Summit, Utah, on May 10, 1869.
