The Act of 1862, which created the Union Pacific Railroad Company, together with the amending Act of 1864, authorized the construction of a main line from an initial point "on the one hundredth meridian of longitude," in the Territory of Nebraska to the eastern boundary of California, with branch lines to be constructed by other companies and to radiate from this initial point to Sioux City, to Omaha, to St. Joseph, to Leavenworth, and to Kansas City. * Provision was made for a subsidy of $16,000 a mile for the level country east of the Rocky Mountains; $48,000 a mile for the lines through mountain ranges; and $32,000 a mile for the section between the ranges. The original plan to secure the government subsidies by a first mortgage on the lines was amended so as to allow private capital to take the first mortgage, the Government taking a second lien for its advances. In addition to these subsidies the several companies were to receive land grants of 12,800 acres to the mile in alternate sections contiguous to their lines. Upon the same terms the Central Pacific, a company incorporated under the laws of California, was authorized to construct a line from the Pacific coast, at or near San Francisco, to meet the Union Pacific Railroad. * These ambitious designs were never fully realized. The main line ran eventually west from Omaha, meeting the Sioux City branch at Fremont. The only other branch which was constructed to connect with the Union Pacific was that from Kansas City and it ran first to Denver. The public was quick to realize the significance of this huge enterprise, for the papers of the day were full of such comments as the following: "It is useless to enlarge upon the value and importance of this great work. It concerns, not the United States alone, but all mankind. Its line is coincident with the natural and convenient route of commerce for the world.... Over it the trip will be made from London to Hong Kong in forty days, over a route possessing every comfort and attraction, which takes a continent in its course, and which, from the variety and magnitude of its sources, from the race which now dominates it, and from the extent of their numbers, wealth and productions, must soon give law to the commercial world."
