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

On May 29, 2018, one of the tunnels, known as Tunnel 11, caved in during scheduled maintenance work, shutting down rail traffic for 3 weeks. Union Pacific rerouted their freight trains running between Northern California and Portland through

The right-of-way is surrounded by waterfalls and streams running through
469-456: A new Union Pacific "Railroad". In the early 20th century, Union Pacific's focus shifted from expansion to internal improvement. Recognizing that farmers in the Central and Salinas Valleys 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 came culminated in

The engine also pulled the president's funeral train on his final journey to College Station in 2018. The Union Pacific system includes hundreds of yards. Most are flat yards used for local switching. Other types of yards include intermodal terminals and hump yards. Most UP intermodal terminals are typically ports, but UP also has inland terminals for transfers to trucks, such as

Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route . Over the next century, UP absorbed the Missouri Pacific Railroad ,
1139-507: The 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. The ensuing financial crisis of 1873 led to

The combined Union Pacific–Central Pacific line became known as the first transcontinental railroad and later the Overland Route . The line was constructed primarily by Irish labor who had learned their craft during the recent Civil War . Under the guidance of its dominant stockholder, Thomas C. Durant ,
1340-822: 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 Los Angeles Union Station on May 2. Since then, Union Pacific has satisfied its common carrier requirements by hosting Amtrak trains. Many Amtrak and commuter rail routes use Union Pacific rails. This list excludes

When Union Pacific bought out the 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 , Northwest Line to Harvard, Illinois , and 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
1943-686: The Chicago area commuter rail system, trains are branded as Metra services and use Metra equipment. However, Union Pacific crews continue to operate the trains under a purchase-of-service agreement. In 2023, UP announced its intentions to surrender the control and operation of commuter rail services and trains in Chicago to Metra , however the UP would retain ownership and control of the right-of-ways of former Chicago & Northwestern lines radiating from Chicago. Between 1869 and 1971, Union Pacific operated passenger service throughout its historic "Overland Route". These trains ran between Chicago and Omaha on

2077-581: 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 streamlined train : the M-10000 . The latter resulted in the Sun Valley ski resort in central Idaho ; it opened in 1936 and finally

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
2211-504: The SP logo on the front is replaced by a Union Pacific shield, and new numbers are applied over the old numbers with a Union Pacific sticker, however some engines remain in Southern Pacific "bloody nose" paint. Over the past couple years, most of the patched units were repainted into the full Union Pacific scheme and as of January 2019, less than ten units remain in their old paint. Among the more notable equipment is: On August 19, 2006, UP unveiled

It extended from New Orleans through Texas to El Paso , across New Mexico and through Tucson , to Los Angeles , through most of California , including San Francisco and Sacramento . Central Pacific lines extended east across Nevada to Ogden, Utah , and reached north through Oregon to Portland . Other subsidiaries eventually included
2479-409: The Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system.

UP also has a collection of locomotives painted for Operation Lifesaver ,

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. The resulting track ran westward from Council Bluffs, Iowa , to meet in Utah

If the typical anarchist conceived that a railroad corporation should be terrorized, he would not scruple to wreck
3149-590: The incident exceeded $ 7 million. Investigations of the Macdona incident revealed several serious safety lapses on the part of the Union Pacific and its employees, including employees not following the company's own safety rules. While the immediate cause of the derailment was the UP crew's "fatigue", chlorine tank cars had been improperly placed near the front of the train, a danger in the case of derailment.

The locomotives commemorate the Missouri Pacific with UP 1982 , the Western Pacific with UP 1983 ,
