Union Pacific in the context of Upper Midwest

Abilene (/ˈæbɪliːn/ AB-i-leen) is a city in Taylor and Jones counties, Texas, United States. Its population was 125,182 at the 2020 census. It is the principal city of the Abilene metropolitan statistical area, which had a population of 176,579 as of 2020. Abilene is home to three Christian universities: Abilene Christian University, McMurry University, and Hardin–Simmons University. It is the county seat of Taylor County. Dyess Air Force Base is located on the west side of the city.

Abilene is located on Interstate 20, which forms a rounded bypass loop along the northern side of the city, between exits 279 on its western edge and 292 on the east. The city is located 150 miles (240 km) west of Fort Worth. Multiple freeways form a loop surrounding the city's core: I-20 on the north, US 83/84/277 on the west, and Loop 322 to the east. The former Texas and Pacific Railway, now part of the Union Pacific mainline, divides the city into well-established north and south zones. The historic downtown area is on the north side of the railroad, while the growing south of downtown Abilene "SODA" district is located on the south side of the tracks.

A crossbuck is a traffic sign used to indicate a level railway crossing. It is composed of two slats of wood or metal of equal length, fastened together on a pole in a saltire formation (resembling the letter X). Crossbucks are often supplemented by electrical warnings of flashing lights, a bell, and/or a boom barrier that descends to block the road and prevent traffic from crossing the tracks.

The Richard B. Ogilvie Transportation Center (/ˈoʊɡəlviː/), on the site of the former Chicago and North Western Terminal, is a commuter rail terminal in downtown Chicago, Illinois, United States. For the last century, this site has served as the primary terminal for the Chicago and North Western Railway and its successors Union Pacific and Metra. Intercity services had disappeared by the 1970s, but commuter services on the three ex-CNW mainlines, Metra's UP District lines, continue to terminate here. The tracks are elevated above street level. The old CNW terminal building was replaced in the mid-1980s with a modern skyscraper, the 500 West Madison Street building. The modern building occupies two square city blocks, bounded by Randolph Street and Madison Street to the north and south and by Canal Street and Clinton Street to the east and west. It is the second busiest rail station in Chicago, after nearby Union Station, the sixth-busiest railway station in North America, and the third-busiest station (after Grand Central Terminal and Jamaica station in New York City) that exclusively serves commuter traffic.

Fort Sanders was a wooden fort constructed in 1866 on the Laramie Plains in southern Wyoming, near the city of Laramie. Originally named Fort John Buford, it was renamed Fort Sanders after General William P. Sanders, who died at the Siege of Knoxville during the American Civil War. This was the second fort to be named after Sanders, the first being in Knoxville, Tennessee. The fort was originally intended to protect travelers on the nearby Overland Trail from Indian attacks, but later the garrison was tasked with protecting the workers of the Union Pacific railroad when it arrived in the spring of 1868. In 1869 the town of Laramie (originally called "Laramie City") was created about 3 miles (4.8 km) north of the fort. Fort Sanders became less important following the construction of Fort D. A. Russell in Cheyenne in 1868, but the War Department maintained it until 1882 when the buildings were sold.

The history of the Union Pacific Railroad stretches from 1862 to the present. For operations of the current railroad, see Union Pacific Railroad; for the holding company that owns the current railroad, see Union Pacific Corporation.

There have been four railroads called Union Pacific: Union Pacific Rail Road, Union Pacific Railway, Union Pacific Railroad (Mark I), and Union Pacific Railroad (Mark II). This article covers the Union Pacific Rail Road (UPRR, 1862–1880), Union Pacific Railway (1880–1897), and Union Pacific Railroad (Mark I)(UP, 1897–1998). For the history of the Union Pacific Railroad (Mark II), see Union Pacific and Southern Pacific Transportation Company.

Altamont Pass, formerly Livermore Pass, is a low mountain pass in the Diablo Range of Northern California between Livermore in the Livermore Valley and Tracy in the San Joaquin Valley. The name is actually applied to two distinct but nearby crossings of the range. The lower of the two, at an elevation of 741 ft (226 m), carries two railroad rights-of-way (ROWs) and Altamont Pass Road, part of the old Lincoln Highway and the original alignment of US 50 before it was bypassed in 1937. The bypass route travels over the higher summit, at 1,009 ft (308 m), and now carries Interstate 580, a major regional highway heavily congested by Central Valley suburbanization.

Of the two railroad lines through the old pass, one is still in use: the ex-Western Pacific line built in 1908 over the pass, which is sometimes known as the Altamont Corridor, now owned by Union Pacific. It carries freight trains as well as the Altamont Corridor Express, which gives its occasional name (ACE) and operates between Stockton, Livermore, Pleasanton, Fremont, and San Jose. The other and older right-of-way was the line built in 1869 with a 1,200-foot-long (370 m) summit tunnel by the original Western Pacific Railroad (1862–1870) as part of the transcontinental railroad. After 1879, when a sea level ferry crossing at the Carquinez Strait replaced the 1869 route, it remained in use for other purposes by the Southern Pacific. In 1984 it was abandoned and deeded to Alameda County by Southern Pacific Railroad in favor of trackage rights on the aforementioned ex-Western Pacific line.

Glenwood Canyon is a rugged scenic 12.5 mi (20 km) canyon in western Colorado in the United States. Its walls climb as high as 1,300 feet (400 m) above the Colorado River. It is the largest such canyon on the Upper Colorado. The canyon, which has historically provided the routes of railroads and highways through western Colorado, currently furnishes the routes of Interstate 70 and the Union Pacific's Central Corridor between Denver and Grand Junction.

Garlock (formerly, Eugeneville) is an unincorporated community in Kern County, California, United States. It is located 6.25 miles (10 km) east-southeast of Saltdale, at an elevation of 2,169 feet (661 m).

A post office operated at Garlock from 1896 to 1904 and from 1923 to 1926.
