Founded in 1862, the original '''Union Pacific Rail Road''' was part of the [[first transcontinental railroad]] project, later known as the [[Overland Route (Union Pacific Railroad)|Overland Route]]. Over the next century, UP absorbed the [[Missouri Pacific Railroad]], the [[Western Pacific Railroad]], the [[Missouri–Kansas–Texas Railroad]] and the [[Chicago, Rock Island and Pacific Railroad]]. In 1995, the Union Pacific merged with [[Chicago and North Western Transportation Company]], completing its reach into the [[Upper Midwest]]. In 1996, the company merged with [[Southern Pacific Transportation Company]], itself a giant system that was absorbed by the [[Denver and Rio Grande Western Railroad]]. 

The '''Union Pacific Railroad Company''' is the principal operating company of [[Union Pacific Corporation]], which are both headquartered at the [[Union Pacific Center]], in [[Omaha, Nebraska]].

Union Pacific has announced plans to acquire the [[Norfolk Southern Railway]] in a deal worth $85 billion. If approved by regulators, it would create the first transcontinental railroad network in the United States.

===Union Pacific in the 19th century===
{{See also|First transcontinental railroad}}

The original company, the "Union Pacific Rail Road", was incorporated on July 1, 1862, under the [[Pacific Railway Acts|Pacific Railroad Act of 1862]]. President [[Abraham Lincoln]] had approved the act, which authorized railroad construction from the [[Missouri River]] to the Pacific to ensure the stability of the Union throughout the [[American Civil War]],<ref>[http://www.cprr.org/Museum/Pacific_Railroad_Acts.html "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 government the use of the same for postal, military, and other purposes] {{webarchive |url=https://web.archive.org/web/20160527113235/http://www.cprr.org/Museum/Pacific_Railroad_Acts.html |date=May 27, 2016 }} 12 Stat. 489, July 1, 1862</ref> but construction was not completed until after the conflict's conclusion.

Under the original bill that formed the basis of the [[Pacific Railway Acts|1862 Pacific Railroad Act]], the Union Pacific Railroad was to be built from the Nevada–Utah border in the west to the Colorado–Kansas border in the east. However, due to intense lobbying by [[Thomas C. Durant|Dr. Thomas Clark Durant]], the eastern terminal was moved to a location where the Union Pacific could link up with the [[Mississippi and Missouri Railroad]] in Iowa.<ref name="Borneman 2010">{{cite book |last=Borneman |first=Walter R. |author-link= |date=2010 |title=Rival Rails: The Race to Build America's Greatest Transcontinental Railroad |url= |location= |publisher=Random House |page=37 |isbn=978-1-4000-6561-5}}</ref><ref>{{cite book |last=Bain |first=David Haward |author-link= |date=1999 |title=Empire Express: Building the First Transcontinental Railroad |url= |location= |publisher=Viking |pages=114–115 |isbn=0-670-80889-X}}</ref> Following the Act's passage, commissioners appointed by Congress began selling stock in the federally chartered Union Pacific Railroad Company. By 1863, Durant had organized the purchase of 2,000 shares, the prerequisite amount of stock sold in order to begin the railroad's construction.<ref>{{cite book |last=White |first=Richard |author-link= |date=2011 |title=Railroaded: The Transcontinentals and the Making of Modern America |url= |location=|publisher=W.W.

The resulting track ran westward from [[Council Bluffs, Iowa]], to meet in Utah the [[Central Pacific Railroad]] line, which had been constructed eastward from [[Sacramento, California]]. The combined Union Pacific–Central Pacific line became known as the [[first transcontinental railroad]] and later the [[Overland Route (Union Pacific Railroad)|Overland Route]].

The UP also purchased the Utah Eastern Railroad and Utah Western Railroad, both Mormon narrow-gauge lines.<ref>Hilton, George W.  ''American Narrow Gauge Railroads,'' p. 536, Stanford University Press, Stanford, California, 1990.</ref>

The original UP was entangled in the [[Crédit Mobilier of America scandal|Crédit Mobilier scandal]], exposed in 1872. As detailed by the [[The Sun (New York City)|''New York 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.<ref>{{Cite book |last=Crawford |first=Jay Boyd |url=https://archive.org/details/creditmobilierof00craw |title=The Credit Mobilier of America: Its Origin and History |date=1880 |publisher=C. W.

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 Railroad|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".<ref>{{Cite book |last=Ripley |first=William Zebina |url=https://archive.org/details/railroadsfinanc01riplgoog |title=Railroads: Finance and Organization |date=1915 |publisher=Longmans, Green, & Company |location=New York |pages=[https://archive.org/details/railroadsfinanc01riplgoog/page/n265 249]–250 |quote=gould.}}</ref>

Extending towards the Pacific Northwest, Union Pacific built or purchased local lines to reach [[Portland, Oregon]].<ref>{{Cite web |title=PNWC-NRHS |url=http://www.pnwc-nrhs.org/hs_or_n.html |access-date=September 7, 2018 |publisher=Oregon-Washington Railroad & Navigation Company}}</ref> Towards Colorado, it built the [[Union Pacific, Denver and Gulf Railway]]: a system combining narrow-gauge trackage into the heart of the Rockies and a standard gauge line that ran south from Denver, across [[New Mexico]], and into Texas.

The Union Pacific Railway would later declare bankruptcy during the [[Panic of 1893]]. The resulting corporate reorganization reversed Gould's name change: Union Pacific "Railway" merged into a new Union Pacific "Railroad".<ref>{{Cite book |last=Solomon |first=Brian |url=https://books.google.com/books?id=d-KLEjzWUq8C&pg=PA35 |title=Union Pacific Railroad |date=2000 |publisher=Voyageur Press |isbn=9781610605595 |pages=35–43}}</ref><ref>{{Cite web |title=Post-Construction |url=https://www.up.com/aboutup/history/overview/post-construction/index.htm |url-status=dead |archive-url=https://web.archive.org/web/20180908092812/https://www.up.com/aboutup/history/overview/post-construction/index.htm |archive-date=September 8, 2018 |access-date=September 7, 2018 |publisher=Union Pacific}}</ref>

===Union Pacific in the 20th century===
In the early 20th century, Union Pacific's focus shifted from expansion to internal improvement. Recognizing that farmers in the [[Central Valley (California)|Central]] and [[Salinas Valley]]s of California grew produce far in excess of local markets, Union Pacific worked with its rival Southern Pacific to develop a spoilage-resistant rail-based transport system. These efforts culminated in the 1906 founding of [[Pacific Fruit Express]], soon to be the world's largest lessee of [[Refrigerator car|refrigerated railcars]].<ref>{{Cite web |title=Pacific Fruit Express Company Forms |url=https://www.up.com/timeline/index.cfm |access-date=September 7, 2018 |publisher=Union Pacific}}</ref>

Meanwhile, Union Pacific worked to construct a faster, and more direct substitute for the original climb to [[Promontory Summit, Utah|Promontory Summit]]. In 1904, the [[Lucin Cutoff|Lucin cutoff]] opened, reducing curvature and grades. The original route would eventually be stripped of track in 1942 to provide [[United States home front during World War II#Local activism|war scrap]].<ref>{{Cite web |title=Lucin Cutoff Opens |url=https://www.up.com/timeline/index.cfm/lucin-cutoff |access-date=September 7, 2018 |publisher=Union Pacific}}</ref>

To attract customers during the Great Depression, Union Pacific's chairman [[W. Averell Harriman]] simultaneously sought to "spruce up" the quality of its rolling stock and to make its unique locations more desirable travel destinations. The first effort resulted in the purchase of the first [[Streamliner|streamlined train]]: the [[M-10000]].<ref>{{Cite web |title=M-10000 Streamliner Debuts |url=https://www.up.com/timeline/index.cfm/m-10000 |access-date=September 7, 2018 |publisher=Union Pacific}} See also in the sidebar: "By 1936, Union Pacific’s shiny new Streamliners had begun to attract passengers back to the railroad, but the Depression was keeping passenger counts low."</ref> The latter resulted in the [[Sun Valley, Idaho|Sun Valley]] [[ski resort]] in central [[Idaho]]; it opened in 1936 and finally was sold in 1964.<ref name="invcharlft">{{Cite news |date=November 29, 2010 |title=Union Pacific Railroad invention still takes skiers to the top |url=http://www.uprr.com/newsinfo/releases/heritage_and_steam/2010/1129_sunvalley-chairlift.shtml |access-date=June 9, 2017 |publisher=Union Pacific Railroad}}</ref><ref name="exhosv">{{Cite web |last=Lund |first=Morten |date=2000 |title=An extraordinary history of Sun Valley |url=https://books.google.com/books?id=k1gEAAAAMBAJ&pg=PA20 |website=Skiing Heritage Journal |pages=20–25}}</ref> Despite the fact that the M-10000 and its successors were among the first diesel locomotives, Union Pacific completed [[Dieselisation|dieselization]] relatively late. In 1944, UP finally received delivery of its last steam locomotive: [[Union Pacific 844]].<ref>{{Cite web |title=UP Receives Its Last New Steam Locomotive |url=https://www.up.com/timeline/index.cfm/last-new-steam-locomotive |access-date=September 7, 2018 |publisher=Union Pacific}}</ref>

As the 20th century waned, Union Pacific recognized—like most railroads—that remaining a regional railroad would only lead to bankruptcy. On December 31, 1925, UP and its subsidiaries operated {{convert|9834|mile}} routes and {{convert|15,265|mile}} tracks;{{Citation needed|date=September 2018}} in 1980, these numbers had remained roughly constant (9,266 route-miles and 15,647 track-miles).<ref>1980 mileage is from ''Moody's Transportation Manual'' (1981); the ICC's ''Transport Statistics'' says Union Pacific System operated 8,614 route-miles at year end 1980, but the 1979 issue says 9,315 route-miles and the 1981 says 9,096, so their 1980 figures look unlikely.</ref> But in 1982, UP acquired the [[Missouri Pacific Railroad|Missouri Pacific]] and [[Western Pacific Railroad|Western Pacific]] railroads, and 1988, the [[Missouri–Kansas–Texas Railroad|Missouri–Kansas–Texas]].<ref name="Trains 2016" /> By 1993, Union Pacific had doubled its system to {{convert|17,385|mile}} routes.

By then, few large (class I) railroads remained. The same year that Union Pacific merged with the [[Chicago and North Western Transportation Company|Chicago and North Western]] (1995), [[Burlington Northern Railroad|Burlington Northern]] and [[ATSF]] announced merger plans. The impending BNSF amalgamation would leave one mega-railroad in control of the west. To compete, UP merged with [[Southern Pacific Transportation Company|Southern Pacific]], thereby incorporating [[Denver and Rio Grande Western Railroad|D&RGW]] and [[St. Louis Southwestern Railway|Cotton Belt]], and forming a duopoly in the West.<ref name="Trains 2016">{{Cite journal |date=November 2016 |title=Mergers since 1980 |journal=[[Trains (magazine)|Trains]] |volume=76 |issue=11 |pages=31 |id={{ProQuest|1820289392}}}} (Sidebar on "Transcon Mergers" article.)</ref> The merged railroad took the Union Pacific name. As of 1999, the UP had {{convert|33,705|miles}} of track, about 33,000 employees, nearly 7,000 locomotives and over 155,000 rail cars.<ref>{{Cite book |last=Solomon, Brian |title=Union Pacific Railroad |date=2000 |publisher=Voyageur Press |isbn=978-1610605595 |page=7}}</ref>

In the late 2010s, Union Pacific began deactivating hump yards in favor of flat switching.

==Locomotives and rolling stock==
Union Pacific has owned some of the most powerful locomotives. These include members of the Challenger-type (including [[Union Pacific 3985|the 3985]]), and the Northern-type (including [[Union Pacific 844|the 844]]), as well as the [[Union Pacific Big Boy|Big Boy]] steam locomotives (including [[Union Pacific 4014|the 4014]]). Union Pacific ordered the [[M-10000|first diesel streamliner]], the [[Union Pacific GTELs|largest fleet of turbine-electric locomotives in the world]], and the [[EMD DDA40X|largest diesel locomotives ever built]] (including [[Union Pacific 6936|6936]]).<ref>{{Cite book |last=Brian Solomon |url=https://books.google.com/books?id=d-KLEjzWUq8C&pg=PA91 |title=Union Pacific Railroad |date=1981 |publisher=Voyageur Press |isbn=9781610605595 |page=91}}</ref>

===Paint and colors===

The yellow paint scheme was introduced in the spring of 1934.

The middle two-thirds of the locomotive body is painted ''Armour Yellow'',<ref>{{Cite web |last=Strack |first=Don |date=August 25, 2015 |title=Armour Yellow on Union Pacific |url=https://utahrails.net/up/armour-yellow.php |access-date=June 23, 2022 |website=UtahRails.net}}</ref> a color used by [[Armour and Company]] on the packaging of its meat products. A thin band of ''Signal Red'' divides this from the ''Harbor Mist Gray'' (a light gray) used for the body and roof above that point. There is also a thin band of Signal Red along the bottom of the locomotive body, but this color has gradually become yellow as new Federal Railroad Administration (FRA) regulations for reflectorized tape came into effect in 2005; the trucks (painted Aluminum from 1955 to 1982), underframe, fuel tanks and everything else beneath that line are also Harbor Mist Gray. Lettering and numbering are in Signal Red, with black outlines. Most locomotives have white-outlined blue "wings" on the nose, on either side of the renowned shield featuring white lettering on a blue background and, below it, red and white vertical stripes. Beginning in early 2002, a number of units were repainted with a large, billowing [[Flag of the United States|American flag]] with the corporate motto "Building America" on the side, where the 'UNION PACIFIC' lettering is normally positioned.{{Citation needed|date=October 2020}}

====Merger partner locomotives====
[[File:UP GP38-2 588.jpg|thumb|A former Southern Pacific [[EMD GP38-2|GP38-2]] locomotive renumbered with UP "patch" markings]]

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. {{As of|2018|03|post=,}} only 41 locomotives remained unpainted.<ref>{{Cite journal |last=Guss |first=Chris |date=March 2018 |title=Perfecting a unified look |journal=[[Trains (magazine)|Trains]] |volume=78 |issue=3 |pages=14 |id={{ProQuest|1988415135}}}}</ref>

From the second half of 2005 to the summer of 2006, UP unveiled a new set of six [[EMD SD70ACe]] locomotives in "Heritage Colors", painted in schemes reminiscent of railroads acquired by the Union Pacific Corporation since the 1980s. The engine numbers match the year that the predecessor railroad became part of the Union Pacific system. The locomotives commemorate the [[Missouri Pacific Railroad|Missouri Pacific]] with [[Union Pacific 1982|UP 1982]], the [[Western Pacific Railroad|Western Pacific]] with [[Union Pacific 1983|UP 1983]], the [[Missouri–Kansas–Texas Railroad|Missouri–Kansas–Texas]] with [[Union Pacific 1988|UP 1988]], the [[Chicago and North Western Railway|Chicago and North Western]] with [[Union Pacific 1995|UP 1995]], the [[Southern Pacific Railroad|Southern Pacific]] with [[Union Pacific 1996|UP 1996]], and the [[Denver and Rio Grande Western Railroad|Denver and Rio Grande Western]] with [[Union Pacific 1989|UP 1989]].<ref>{{Cite press release |title=Denver & Rio Grande Western Colors Again Ride the Rails |date=June 19, 2006 |publisher=Union Pacific Railroad |url=http://www.uprr.com/newsinfo/releases/heritage_and_steam/2006/0619_drgw.shtml |access-date=April 20, 2010}}</ref>

In October 2005, UP unveiled SD70ACe [[Union Pacific 4141|4141]], commissioned in honor of [[George H. W. Bush|George Bush]]. The locomotive has "[[George H. W.

===Commuter services===
When Union Pacific bought out the [[Chicago & North Western Transportation Company|Chicago & North Western]] in 1995, it inherited the railroad's [[Metra]] commuter rail services in the [[Chicago metropolitan area]]: the [[Union Pacific North Line]] to [[Kenosha, Wisconsin]], [[Union Pacific Northwest Line|Northwest Line]] to [[Harvard, Illinois]], and [[Union Pacific West Line|West Line]] to [[Elburn, Illinois]], all of which operate from [[Ogilvie Transportation Center]] (the former North Western Station–a name still used by many Chicago residents). In order to ensure uniformity across the Chicago area commuter rail system, trains were branded as Metra services and used Metra equipment. However, Union Pacific crews operated the trains under a purchase-of-service agreement.<ref>{{Cite news |last=Lassen |first=David |date=July 22, 2020 |title=STB filings detail Metra, UP disagreement (updated) |url=https://trn.trains.com/news/news-wire/2020/07/22-stb-filings-detail-metra-up-disagreement |url-status=dead |archive-url=https://web.archive.org/web/20200729164742/https://trn.trains.com/news/news-wire/2020/07/22-stb-filings-detail-metra-up-disagreement |archive-date=July 29, 2020 |access-date=July 29, 2020 |agency=Trains Magazine}}</ref><ref name="Metra-History">{{Cite web |date=August 10, 2018 |title=Metra History |url=https://metrarail.com/about-metra/our-history |url-status=dead |archive-url=https://web.archive.org/web/20190308002617/https://www.metrarail.com/about-metra/our-history |archive-date=March 8, 2019 |access-date=August 10, 2018 |publisher=Metra}}</ref> In 2025, UP transferred the control and operation of its commuter rail services and trains in Chicago to [[Metra]]. UP retains ownership of the right-of-ways of former [[Chicago & Northwestern]] lines radiating from Chicago and continues to oversee dispatching.

===Former services===
[[File:Wine label Roma Wine Company Union Pacific RR.jpg|thumb|Wine label, Roma Wine Company, bottled for Union Pacific RR circa 1940s]]
Between 1869 and 1971, Union Pacific operated passenger service throughout its historic "Overland Route". These trains ran between Chicago and Omaha on the [[Chicago & Northwestern]] trackage starting in 1936. Disputes over trackage rights and passenger revenues with the C&NW prompted the UP to switch to the [[Milwaukee Road]] for the handling of its streamliner trains between Chicago and Omaha beginning in late 1955.  The last intercity passenger train operated by UP was the westbound ''City of Los Angeles'', arriving at [[Union Station (Los Angeles)|Los Angeles Union Station]] on May 2, 1971.<ref>''See'' Solomon, Brian, ''Railroad Color History: Union Pacific Railroad'', p. 72 (photo of last westbound ''City of Los Angeles'' taken at Las Vegas on May 2, 1971).

The pollutants are mostly petroleum [[hydrocarbon]]s, industrial solvents, and metals.<ref>{{Cite web |title=Union Pacific Railyard Cleanup, Eugene |url=http://www.deq.state.or.us/lq/cu/wr/UPRREugene/index.htm |archive-url=https://web.archive.org/web/20080526051327/http://www.deq.state.or.us/lq/cu/wr/uprreugene/index.htm |archive-date=May 26, 2008 |access-date=March 29, 2009 |publisher=Oregon Department of Environmental Quality}}</ref>

In 2007, Union Pacific Railroad worked with the [[US EPA]] to develop a way to reduce locomotive exhaust emissions. They discovered that adding an oxidation catalyst filtering canister to the diesel engine's exhaust manifold and using [[Ultra-low-sulfur diesel|ultra-low-sulfur diesel fuel]] would reduce particulate emissions by about half, unburned hydrocarbons by 38&nbsp;percent, and carbon monoxide by 82&nbsp;percent.<ref>{{Cite web |date=January 18, 2007 |title=Union Pacific Tests Exhaust Catalyst on Locomotives |url=http://www.environmentalleader.com/2007/01/18/union-pacific-tests-exhaust-catalyst-on-locomotives/ |archive-url=https://web.archive.org/web/20081009013218/http://www.environmentalleader.com/2007/01/18/union-pacific-tests-exhaust-catalyst-on-locomotives/ |archive-date=October 9, 2008 |access-date=May 8, 2008 |website=Environmental Leader}}</ref>

The company's Fuel Master program rewards locomotive engineers who save the most [[fuel]] each month. The program has saved the company millions of dollars, much of which has been returned to the engineers. In 2006, the program's founder, Wayne Kennedy, received the John H. Chafee Environmental Award, and the program was recognized by Transportation Secretary [[Norman Mineta]].<ref>{{Cite web |title=Green Car Congress: DOT Secretary Commends Union Pacific's Conservation Program, Says US Needs to Go on Energy Diet |url=http://www.greencarcongress.com/2006/02/dot_secretary_c.html |access-date=October 29, 2015 |website=GreenCarCongress.com |publisher=BioAge Media}}</ref>

In January 2018, a former waste water operator at Union Pacific Albina Yard in [[Portland, Oregon]], employed by the railroad's contractor [[Mott MacDonald]] negligently released thousands of gallons of oil into the environment. The operator was distracted by a cell phone and allowed the tank to overflow for over an hour. An engineering firm hired by Union Pacific estimates 1,800 U.S. Gallons (6,813.741 L) of it was released into nearby [[Willamette River]], not including the spill that was captured by the containment booms. Employees of [[United States Environmental Protection Agency]] who were working at facilities nearby placed booms to contain the oil spill. Federal prosecutors have charged the operator Robert LaRue Webb II with violation of the [[Clean Water Act]] for releasing the oil into the environment. Webb pleaded guilty in August 2019,<ref>{{Cite web |date=August 5, 2019 |title=Portland Man Pleads Guilty to Clean Water Act Violation for Discharging Oil into Willamette River |url=https://www.justice.gov/usao-or/pr/portland-man-pleads-guilty-clean-water-act-violation-discharging-oil-willamette-river |access-date=November 4, 2019 |website=Department of Justice - U.S. Attorney's Office}}</ref> and was sentenced to two years probation and a $2,500 fine.<ref>{{Cite web |last=Bernstein |first=Maxine |date=June 24, 2019 |title=Union Pacific plant operator allowed thousands of gallons of oil to spill into Willamette River, feds say |url=https://www.oregonlive.com/environment/2019/06/union-pacific-plant-operator-allowed-thousands-of-gallons-of-oil-to-spill-into-willamette-river-feds-say.html |access-date=November 2, 2019 |website=oregonlive}}</ref><ref>{{Cite web |last=Bernstein |first=Maxine |date=October 28, 2019 |title=Former Union Pacific Plant Officer Who Allowed Gallons of Oil to Seep into Willamette River Gets Probation |url=https://www.oregonlive.com/crime/2019/10/former-union-pacific-plant-officer-who-allowed-gallons-of-oil-to-seep-into-willamette-river-gets-probation.html |access-date=November 2, 2019 |website=oregonlive}}</ref><ref>{{Cite web |date=October 29, 2019 |title=Ex-Railroad Plant Operator Who Allowed Oil Spill Sentenced |url=https://apnews.com/d02fabd3a2ef4b03b64fffe04eced553 |access-date=November 2, 2019 |website=AP NEWS}}</ref>

In 2016, the Union Pacific Railroad Co. was named as a defendant in a lawsuit seeking cleanup of a contaminated rail yard site that operated in [[Lafayette, Louisiana]], from the late 1800s until the 1960s.<ref>{{Cite web |last=Burgess |first=Richard |date=February 5, 2016 |title=Landowners sue to get Lafayette railroad yard cleaned up, concerned about contamination of aquifer: Potential threat to Chicot Aquifer cited |url=https://www.theadvocate.com/acadiana/news/article_426b44fd-9b74-5479-8d2c-969818f180dd.html |access-date=November 9, 2021 |website=The Advocate}}</ref>

In 2020, [[Houston]] residents living near a Union Pacific Railroad Company rail yard filed lawsuits against the Union Pacific. These lawsuits followed the finding by the State of Texas of a higher-than-expected incidence of certain cancers in residents living close to the yard.<ref>{{Cite web |last=Douglas |first=Erin |date=September 19, 2020 |title=Residents Sue Union Pacific, Others over Cancer Deaths |url=https://infoweb.newsbank.com/apps/news/document-view?p=AWNB&t=country%3AUSA%21USA&sort=YMD_date%3AD&fld-base-0=alltext&maxresults=20&val-base-0=lawsuit%20%22union%20pacific%22%20Houston%20railyard&docref=news/17DB0F01C28BCF48 |access-date=November 9, 2021 |website=NewsBank |publisher=Houston Chronicle}}</ref> A State of Texas report released in 2021 identified an additional [[cancer cluster]] of [[lymphoblastic leukemia]] in children.<ref>{{Cite web |last=Ernst |first=Sara Willa |date=February 3, 2021 |title='We Know What We Want': 5th Ward Residents Demand Action after Another Confirmed Cancer Cluster |url=https://www.houstonpublicmedia.org/articles/news/health-science/2021/02/03/390571/5th-ward-cancer-cluster-houston-confirmed/ |access-date=November 9, 2021 |publisher=Houston PBS}}</ref>

In 2022, the state of Utah proposed bill, HB405, which would have required Union Pacific to replace their aging fleet of [[United States vehicle emission standards#Non-road engines|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 [[Mike Schultz (politician)|state Rep. Schultz]], Union Pacific was uncooperative on the switching locomotive bill if Utah did not drop the railroad crossings bill. 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.<ref name="Deseret News 2022" /><ref name="Trains 2022" />

Wabtec is modernizing 600 older Union Pacific locomotives over a three-year period through 2025.
