Selective Door Opening
Selective door operation (SDO), also known as selective door opening, is a mechanism employed primarily on trains (although buses with multiple doors also generally have this feature) that allows the driver or conductor/guard to open the doors of a train separately. Selective Door Operation enables trains to call at a station where the platform is shorter than the train. Some doors can be prevented from opening to ensure that passengers do not disembark from any carriages not standing at the platform. The term Selective Door Operation is used mainly in the United Kingdom; some train operating companies used the term ‘Door De-Select’. A version of this is used in other countries and on other rail systems such as the London Underground. UK variations In the UK various trains, either multiple units or coaches, have variations of the selective door operating system. This usually depends on what the specific train operating company and/or train leasing company required, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train
In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive in the United Kingdom in 1804, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Class 373
The British Rail Class 373 or TGV TMST, sometimes referred to as Eurostar e300, is a French designed and Anglo-French built electric multiple unit train that is used for Eurostar international high-speed rail services from the United Kingdom to France and Belgium through the Channel Tunnel. Part of the TGV family, it was built with a smaller cross-section to fit the smaller loading gauge in Britain, was originally capable of operating on the UK third rail network, and has extensive fireproofing in case of fire in the tunnel. It is both the second longest——and second fastest train in regular UK passenger service, operating at speeds of up to . Known as the TransManche Super Train (TMST) or Cross-channel Super Train before being introduced in 1993, the train is designated Class 373 under the British TOPS classification system and series 373000 TGV in France. It was built by the French company GEC-Alsthom at its factories in La Rochelle (France), Belfort (France) and Washwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 331
The British Rail Class 331 '' Civity'' is a class of electric multiple unit built by CAF, owned by Eversholt Rail Group, and currently operated by Northern Trains. A total of 43 units have been built31 three-car units and 12 four-car units. Construction of the trains started in July 2017 and they were phased into service from 1 July 2019. History The announcement of the new trains was made by Arriva UK Trains when it was confirmed that it would become the next operator of the Northern franchise from 1 April 2016. CAF were selected by Arriva as they were the only manufacturer able to produce both new diesel () and electric multiple units from the same platform, the '' Civity'', thus increasing familiarity for drivers and reducing maintenance costs once in operation. Bombardier submitted a bid to produce electric units based on their new ''Aventra'' platform, but was unable to offer the matching DMU that Arriva required. Furthermore, Bombardier already had a long order book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 195
The British Rail Class 195 '' Civity'' is a class of diesel multiple-unit passenger train manufactured by CAF, owned by Eversholt Rail Group and currently operated by Northern Trains. A total of 58 units have been built; 25 two-car units and 33 three-car units. The class is almost identical to the Class 331 also produced by CAF, which is the electric version of the Class 195, differing only in traction type and (in some units) vehicle formation. They were first introduced on 1 July 2019, entering service with the previous operator Arriva Rail North on the Manchester Airport and Liverpool Lime Street via Warrington, and Manchester Airport to Barrow-in-Furness routes. The final 195 unit entered service in December 2020 and all 58 units work across all non-electrified routes across the Northern network. History The introduction of new rolling stock for the Northern franchise was fuelled by the need to phase out the unpopular '' Pacer'' trains by 2020. The tender for the then-n ...

Balise
A balise is an electronic beacon or transponder placed between the rails of a railway as part of an automatic train protection (ATP) system. The French word '' balise'' is used to distinguish these beacons from other kinds of beacons. Balises are used in the KVB signalling system installed on main lines of the French railway network, other than the high-speed Lignes à Grande Vitesse. Balises constitute an integral part of the European Train Control System, where they serve as "beacons" giving the exact location of a train. The ETCS signalling system is gradually being introduced on railways throughout the European Union. Balises are also used in the Chinese Train Control System versions CTCS-2 and CTCS-3 installed on high-speed rail lines in China, which is based on the European Train Control System. A balise which complies with the European Train Control System specification is called a Eurobalise. Overview A balise typically needs no power source. In response to radi ...

Govia Thameslink Railway
Govia Thameslink Railway (GTR) is a train operating company that operates the Thameslink, Southern and Great Northern (TSGN) rail franchise in England. Within the franchise, GTR runs the Thameslink, Great Northern, Southern and Gatwick Express services. GTR is a subsidiary of Govia, which is itself a joint venture between the British Go-Ahead Group (65%) and French company Keolis (35%). The franchise was awarded, after repeated delays, to Govia Thameslink Railway on 23 May 2014. On 14 September 2014, GTR took over operations for the prior franchisee First Capital Connect; during July 2015, both Southern and Gatwick Express operations were integrated into GTR. This change made it the largest rail franchise in terms of passengers, staff and fleet in the UK. The franchise has an unusual structure involving a management contract that sees all fare revenues going straight to the Department for Transport (DfT), which in turn pays GTR fixed amounts that add up to £8.9 billion a ...

Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was lau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 387
The British Rail Class 387 is a type of electric multiple unit passenger train built by Bombardier Transportation as part of the Electrostar family. A total of 107 units were built, with the first train entering service with Thameslink in December 2014. The trains are currently in service with Great Western Railway, Govia Thameslink Railway, and Heathrow Express. The Class 387 is a variation of the '' Bombardier Electrostar'', albeit with dual-voltage capability (which allows units to run on 750VDC third rail as well as use 25kVAC OLE). The class were the final rolling stock orders based on the Bombardier Electrostar family with 2,805 vehicles built over 18 years between 1999 and 2017. Description Class 387/1 The first Class 387/1s were ordered for the Thameslink route, which enabled the existing units to be transferred to Northern Rail for use on the newly electrified Manchester Victoria to Liverpool via Newton-le-Willows route.

British Rail Class 379
The British Rail Class 379 ''Electrostar'' is an electric multiple-unit (EMU) passenger train designed and built by the rolling-stock manufacturer Bombardier Transportation. The trains are part of the company's extensive Electrostar family. The Class 379 was specifically procured in response to a government white paper issued in 2007, under which £185 million of investment was issued to the West Anglia Main Line (WAML), the bulk of which was spent with Bombardier Transportation to procure the 30-strong Class 379 fleet of EMUs. While the type was largely intended to increase capacity, its introduction did enable the withdrawal of ageing units such as the Class 317 EMUs; the programme also involved various infrastructure improvements. The Class 379's introduction was relatively smooth and brought about a noticeable step up in service quality. Since their introduction during early 2011, the Class 379 became the principal type operated on the Stansted Express service; it was also ...

British Rail Class 378
The British Rail Class 378 ''Capitalstar'' is an electric multiple unit passenger train specifically designed for the London Overground network. It is part of Bombardier Transportation's Electrostar family. A total of 57 five-car trains have been built - most of which were originally built as three- or four-car units. The Class 378s were ordered in August 2006 in response to passenger dissatisfaction with existing mass-transit trains operated by Silverlink, such as the ageing fleet of Class 313. The procurement of a modern replacement was viewed as yielding better performance than the refurbishment of the existing units. Accordingly, a total of 57 Class 378s were manufactured at Bombardier's Derby site, the first example of which entered revenue service during July 2009. The type's introduction was roughly half a year later than originally planned, largely as a result of difficulties with multiple suppliers. In design terms the train is broadly similar to the Class 376 tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
