The Union Pacific Railroad , headquartered in Omaha, Nebraska, is the largest railroad network in the United States. James R. Young is Chairman. UP's route map covers most of the central and western United States west of Chicago and New Orleans. As of December 31, 2008 UP operates on 32,012 miles of track, of which it owns outright 26,171 miles . Both numbers represent the highest amount of any railroad currently operating in the United States. It has achieved this size as a result of purchasing a large number of other railroads, notably the Missouri Pacific, Chicago and North Western,... Western Pacific, Missouri-Kansas-Texas, and the Southern Pacific . Currently, Union Pacific owns 26% of Ferromex while Grupo Mexico owns the remaining 74%. UP's chief railroad competitor is the BNSF Railway, which covers much of the same territory in the United States. The original company, prior to later uniting with the Central Pacific Railroad, was incorporated on July 1, 1862 under an act of Congress entitled Pacific Railroad Act of 1862.
