Tehachapi Loop
The Tehachapi Loop is a long spiral, or helix, on the Union Pacific Railroad Mojave Subdivision through Tehachapi Pass, of the Tehachapi Mountains in Kern County, south-central California. The line connects Bakersfield and the San Joaquin Valley to Mojave in the Mojave Desert. Rising at a steady two-percent grade, the track gains in elevation and makes a diameter circle. Any train that is at least 3,800 feet (1,162 m) (approx. 56 60’(67'11") box cars) long passes over itself going around the loop. At the bottom of the loop, the track passes through Tunnel 9, the ninth tunnel built as the railroad was extended from Bakersfield. The line averages about 36 freight trains each day; passenger services such as Amtrak's ''San Joaquin (Amtrak), San Joaquin'' are banned from using the loop, while the ''Coast Starlight'' can only use it as a detour. Its frequent trains and scenic setting make the Tehachapi Loop popular with railfans. In 1998, it was named a National Historic Civ ...

Mojave Desert
The Mojave Desert ( ; mov, Hayikwiir Mat'aar; es, Desierto de Mojave) is a desert in the rain shadow of the Sierra Nevada mountains in the Southwestern United States. It is named for the indigenous Mojave people. It is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran, Chihuahuan, and Great Basin deserts, forms a larger North American Desert. Of these, the Mojave is the smallest and driest. The Mojave Desert displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between . It supports a diversity of flora and fauna. The desert supports a number of human activities, including recreation, ranching, and military training. ...

San Bernardino Train Disaster
The San Bernardino train disaster (sometimes known as the Duffy Street incident), was a combination of two separate but related incidents that occurred in San Bernardino, California, United States: a runaway train derailment on May 12, 1989; and the subsequent failure on May 25, 1989, of the Calnev Pipeline, a petroleum pipeline adjacent to the tracks which was damaged by earth-moving equipment during the crash cleanup.

Siding (rail)
A siding, in rail terminology, is a low-speed track section distinct from a running line or through route such as a main line, branch line, or spur. It may connect to through track or to other sidings at either end. Sidings often have lighter rails, meant for lower speed or less heavy traffic, and few, if any, signals. Sidings connected at both ends to a running line are commonly known as loops; those not so connected may be referred to as single-ended or dead-end sidings, or (if short) stubs. Functions Sidings may be used for marshalling (classifying), stabling, storing, loading, and unloading vehicles. Common sidings store stationary rolling stock, especially for loading and unloading. Industrial sidings (also known as spurs) go to factories, mines, quarries, wharves, warehouses, some of them are essentially links to industrial railways. Such sidings can sometimes be found at stations for public use; in American usage these are referred to as team tracks (after the use ...

Arthur De Wint Foote
Arthur De Wint Foote (1849–1933) was an American civil engineer and mining engineer who impacted the development of the American West with his innovative engineering works and entrepreneurial ventures. In Northern California in the late 1890s, he designed and built the North Star Mine Powerhouse, the highest capacity impulse-turbine power-plant of the time, and now a California historic landmark; within that plant he designed and installed the then-largest Pelton wheel turbine. Later, he designed and built Foote's Crossing, a high bridge, and Foote's Crossing Road, both now memorialized as California and U.S. landmarks. Early years Born in Guilford, Connecticut, Foote's ancestry was English—from Yorkshire before 1630. After preparatory schooling as a youth, he attended Yale College's Sheffield Scientific School, but left in 1868 before graduating. From there he began his early career in business and construction ventures along the eastern seaboard of the US and in the We ...

Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials- SP) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint, a compa ...
