, exposed in 1872. As detailed by ''The Sun'', Union Pacific's largest construction company, Crédit Mobilier, had overcharged Union Pacific; the railroad would then pass the inflated costs on to the United States government. To convince the federal government to accept the increased costs, Crédit Mobilier had bribed multiple congressmen. Several prominent UP board members (including Durant) had been involved in the scheme. The ensuing financial crisis of 1873 led to a credit crunch, but not bankruptcy. As boom followed bust, the Union Pacific continued to expand. A new company, with dominant stockholder Jay Gould, purchased the old on January 24, 1880. Gould already owned the Kansas Pacific (originally called the Union Pacific, Eastern Division, though in essence a separate railroad), and sought to merge it with UP. Through that merger, the original "Union Pacific Rail Road" transformed into "Union Pacific Railway." Extending towards the Pacific Northwest, Union Pacific built or purchased local lines to reach

Union Pacific has owned some of the most powerful locomotives.

Merger partner locomotives

Until 2017, UP operated some locomotives still in the paint scheme of their former railroads. In addition, some locomotives were renumbered by UP, varying in the degree of the previous railroads' logos being eradicated, but always with a yellow patch applied over the locomotive's former number and a new UP number applied on the cab. That allowed UP to number locomotives into its roster without spending the time and money necessary to perform a complete repaint. In May 2015, UP rostered 212 "patches", consisting of: * 22 Chicago and North Western (whose CNW logos have been hidden by the "patches"), * 174 Southern Pacific (AC4400CW, GP40-2, MP15AC, and GP60) * 14 St. Louis Southwestern (GP60) * 2 Denver and Rio Grande Western (GP60) *While not technically a predecessor locomotive in the traditional sense, UP also rostered a single SD40-2 (3564, since retired) still in the 1970s paint scheme, not counting DDA40X No. 6936, which was part of the Union Pacific Heritage Fleet until 2022. In 2017, Union Pacific decided to repaint all locomotives which were not in the current corporate colors. , only 41 locomotives remained unpainted.

2022 Utah Legislative Action

In 2022, Legislators in Utah brought forth two separate bills specifically aimed at Union Pacific. The first, HB181, was raised after some municipalities encountered resistance from Union Pacific when attempting to upgrade rail crossings. In

, Union Pacific altered a construction agreement to require the city to pay maintenance fees in perpetuity for an upgraded crossing, a mandate which was against state code. The proposed legislation would make it easier for municipalities to get crossing improvements approved, and clarifies which party must pay associated maintenance costs. The second bill, HB405, would have required Union Pacific to replace their ageing fleet of Tier 0 switching locomotives with hydrogen or electric engines by 2028, due to Utah having very poor air quality in winter months. According to Utah Senator Schultz, Union Pacific was uncooperative on the switching locomotive bill if Utah did not drop the railroad crossings bill. Ultimately, HB181 passed, and HB405 was dropped after Union Pacific made voluntary commitments to replace several tier 0 switching locomotives with less polluting tier 2 locomotives, as well as to test some all electric ones in the Utah Roper Rail Yard.
