20-829: The Elko Subdivision is a railway line in Nevada owned and operated by the Union Pacific Railroad running from Weso (switching point just east of Winnemucca ) to the freight yard in Elko . It is part of both the Overland Route and the Central Corridor . The line generally follows the Humboldt River and has several small tunnels while traversing the Palisade and Carlin Canyons ,
40-528: A break of gauge occurred, prior to an Act of Parliament the issue in 1846 by establishing one standard gauge of 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ). The early effort towards standardisation somewhat influenced railways aboard as well, however various other track gauges persisted and developed across the world; even through to the twenty first century, incompatible track gauges, let alone other issues, persisted to hinder interoperability efforts. Several key events happened during
60-514: A rail siding called Harney, between Beowawe and Palisade . In the 1980s both tracks were relocated out of downtown Elko along the banks of the Humboldt River , resulting in Elko having two historical train depots downtown, with neither connected to track today. The Southern Pacific Railroad depot (for westbound passengers) was at 683 Railroad street, while the Western Pacific (eastbound) depot
80-624: Is "to promote rail transport at world level and meet the challenges of mobility and sustainable development." The UIC's main objectives are to: When founded in 1922 the UIC had 51 members from 29 countries, including Japan and China . They were soon joined by members from the Soviet Union , the Middle East and North Africa. As of February 2024, the UIC has 223 members (include suspended) across five continents. Of these there are: On 12 November 2010,
100-504: Is an international rail transport industry body. The railways of Europe had originated during the nineteenth century as many separate concerns across numerous nations; this led to disparate and conflicting standards emerging and thus onto incompatibility. One prominent example was the British Gauge War , during which different railway companies were laying different track gauges across Great Britain , causing inefficiency wherever
120-458: The GSM-R radio telecommunication system was formulated as an international interoperability specification covering voice and signalling systems for railway communications. GSM-R, which is built on GSM technology, was designed to be a cost efficient digital replacement for various existing incompatible in-track cable and analogue railway radio networks. The specification for GSM-R is maintained via

Also see Reverser handle . A metal casting incorporating a slot that allows the casting to fit over the rail near the wheel of a derailed car. The locomotive then pushes or pulls the car so that
160-660: The 1860s by the Central Pacific Railroad , while the eastbound track was built by the Western Pacific Railroad as part of the Feather River Route , between 1906 and 1909. The two tracks generally follow each other, however, the routes are not identical. This results in several oddities in the Elko Subdivision. For example, the community of Battle Mountain is only accessible by westbound trains, as
180-462: The UIC has formed various partnerships and cooperative frameworks with other multinational railway authorities, such as the European Union Agency for Railways . The UIC has played a leading role in the development of Technical Specifications for Interoperability (TSIs), which have gradually taken over from older standards developed by various national railway entities. During the 1990s,
200-482: The UIC opened an African regional office in Tunis , Tunisia with the support of SNCFT . On 9 March 2022, the UIC suspended all member companies from Russia and Belarus, following Russian invasion of Ukraine . In order to provide a common understanding and reduce potential confusion, the UIC has established standard international railway terminology and a trilingual (English-French-German) thesaurus of terms. The thesaurus
220-602: The UIC project European Rail Traffic Management System (ERTMS). By June 2023, GSM-R had been implemented across roughly 130,000km of track, along with 90,000 cab radios and 20,000 datalink radio units. A more capable next-generation radio, the Future Railway Mobile Communication System (FRMCS) program, is under development as of 2023. In addition to eventually replacing GSM-R, it will provide new capabilities that require more rapid data exchange, such as live video transmission. The UIC's mission

#1732868739951240-459: The Western Pacific built track used for eastbound trains is routed several miles to the north of Battle Mountain. The North Valmy Generating Station resides between the two tracks, and the feeders from each track can be used as a crossover for trains to turn around. Also unique, the two tracks have a grade separated crossover near Palisade . As a result, trains in the eastern half of the Elko Subdivision observe right hand traffic , while trains in

280-533: The early twentieth century; in the aftermath of the First World War and the Treaty of Versailles , numerous border changes were enacted across Europe, which greatly impacted several formerly united national railway networks while compelling several others together in some cases. It was early into the interwar period that the UIC was established on 17 October 1922 with the principal aim of standardising practices across
300-693: The engineers and managers who built the inaugural rail infrastructure . An example is the term railroad , used (but not exclusively) in North America , and railway , generally used in English-speaking countries outside North America and by the International Union of Railways . In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist. Various terms, both global and specific to individual countries, are listed here. The abbreviation "UIC" refers to terminology adopted by
320-454: The longest tunnel is called the Carlin Tunnel . The Elko subdivision is unique in that the entire subdivision is operated as a dual track main, but each of the two tracks in the main were formerly competing lines, built by different companies and at different times, that were combined with directional running . The westbound track was part of the first transcontinental railroad built in
340-683: The railway industry and expanding international cooperation in the sector. The UIC has introduced numerous classification systems over the decades. During the 1970s, the UIC Franc currency equivalent was established for the purpose of easing international ticket revenue sharing; it was replaced by the European Currency Unit on 1 January 1990. UIC classification and UIC Country Codes allowed precise determination of rolling stock capabilities and ownership; furthermore, wagons have been assigned their own unique UIC wagon numbers . Over time,
360-619: The western half observe left hand traffic . This shared track arrangement continues east of the Elko freight yards, where the line becomes the Shafter Subdivision until Alazon, Nevada (near Wells ). At Alazon, the two lines separate, with the Central Corridor proceeding to Salt Lake City , while the Overland Route proceeds to Ogden, Utah . The 1939 City of San Francisco derailment occurred along today's Elko Subdivision, near
380-409: Was at the corner of 3rd and Silver streets. Railway line Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins of
400-569: Was the result of cooperation with the European Conference of Ministers of Transport (ECMT/ CEMT ) and was published in 1995. The UIC has established systems for the classification of locomotives and their axle arrangements , coaches and goods wagons . UIC plays an important role in standardization of railway parts, data and terminology, though the degree to which its standards have been adopted by its members varies. Therefore, UIC codes (also known as UIC leaflet ) are developed since
