Judah's interest in a special California road coincided well with the needs and desires of Congress. Already various bills were in the hands of the select committees of both houses. The southern interest was gone. The only remaining rivalries were among St. Louis, Chicago, and the new Minnesota; while the first of these was tainted by the doubtful loyalty of Missouri, and the last was embarrassed by the newness of its territory and its lack of population. The Sioux were yet in control of much of the country beyond St. Paul. Out of this rivalry Chicago and a central route could emerge triumphant. The spring of 1862 witnessed a long debate over a Union Pacific railroad to meet the new military needs of the United States as well as to satisfy the old economic necessities. Why it was called "Union" is somewhat in doubt. Bancroft thinks its name was descriptive of the various local roads which were bound together in the single continental scheme. Davis, on the contrary, is inclined to believe that the name was in contrast to the "Disunion" route of the thirty-second parallel, since the route chosen was to run entirely through loyal territory. Whatever the reason, however, the Union Pacific Railroad Company was incorporated on the 1st of July, 1862. Under the act of incorporation a continental railway was to be constructed by several companies. Within the limits of California, the Central Pacific of California, already organized and well managed, was to have the privilege. Between the boundary line of California and Nevada and the hundredth meridian, the new Union Pacific was to be the constructing company. On the hundredth meridian, at some point between the Republican River in Kansas and the Platte River in Nebraska, radiating lines were to advance to various eastern frontier points, somewhat after the fashion of Benton's bill of 1855. Thus the Leavenworth, Pawnee, and Western of Kansas was authorized to connect this point with the Missouri River, south of the mouth of the Kansas, with a branch to Atchison and St. Joseph in connection with the Hannibal and St. Joseph of Missouri. The Union Pacific itself was required to build two more connections; one to run from the hundredth meridian to some point on the west boundary of Iowa, to be fixed by the President of the United States, and another to Sioux City, Iowa, whenever a line from the east should reach that place.
