The bill creating the Union Pacific Railroad was known as the "Curtis Bill" from its author, Congressman S. R. Curtis of Iowa. It carried the title of "An Act to aid in the construction of a railroad and telegraph line from the Missouri River to the Pacific Ocean and to secure to the United States Government, the use thereof for postal, military, and other purposes." This act passed the Senate, June 20th, 1862, by a vote of thirty-five to two and became a law July 1st, of that same year. In addition to creating the Union Pacific Railroad Company it also authorized the Central Pacific Railroad Company to build a railroad from Sacramento to the eastern boundary of California, where it was to connect with the Union Pacific Railroad. The bill also recognized a Company chartered by the legislature of Kansas under the name of the Leavenworth, Pawnee and Western Railway Company, later known as the Kansas Pacific Railway. This latter line was to be built from Leavenworth west to a junction with the Union Pacific Railroad at or near the hundredth Meridian or about two hundred and fifty miles west of Omaha. The principal features of the bill so far as the Union Pacific Railroad were concerned, were, the creation of a Board of Commissioners consisting of one hundred and fifty-eight commissioners to represent the interest of the United States Government and who were to be named by the Secretary of the Interior. These were to constitute a preliminary organization. The Union Pacific Railroad proper was to commence at a point on the hundredth Meridian, west of Greenwich, between the Valley of the Platte River on the north and the Valley on the Republican River on the south, with branch lines to be known as the Iowa Branch from said point to the Missouri River. On the west it was to extend to the Eastern boundary of California, where it was to connect with the Central Pacific Railroad.
