Thameslink is a 24-hour main-line route in the British railway system, running from Bedford, Luton, St Albans City, Peterborough and Cambridge via central London to Sutton, Orpington, Sevenoaks, Rainham, Horsham, Brighton, East Grinstead, and Littlehampton. The network opened as a through service in 1988, with severe overcrowding by 1998, carrying more than 28,000 passengers in the morning peak. All the services are currently operated by Govia Thameslink Railway.
Southern is the brand name used by the Govia Thameslink Railway (GTR) train operating company on the Southern routes of the Thameslink, Southern and Great Northern franchise in England. It is a subsidiary of Govia, a joint venture between transport groups Go-Ahead and Keolis, and has operated the South Central rail franchise since August 2001 and the Gatwick Express service since June 2008. When the franchise was subsumed into GTR, Southern was split from Gatwick Express and the two became separate brands, alongside the Thameslink and Great Northern brands.
Network SouthEast (NSE) was one of the three passenger sectors of British Rail created in 1982. NSE mainly operated commuter rail trains within Greater London and inter-urban services in densely populated South East England, although the network went as far west as Exeter. Before 1986, the sector was originally known as London & South Eastern.
The British Rail Class 312 alternating current (AC) electric multiple units (EMUs) were built between 1975 and 1978 for use on outer-suburban passenger services. It was the last class of multiple unit to be constructed with the British Rail Mark 2 bodyshell, as well as the last class of multiple unit to be built with slam doors in Britain. These features contributed to their relatively early withdrawal at 25–28 years old, compared with a typical EMU life expectancy of 30–40 years.
The British Rail Class 317 is an electric multiple unit (EMU) passenger train constructed by British Rail Engineering Limited in two batches, 48 sets being produced in 1981–82 and 24 sets in 1985–87. They were the first of several classes of British Rail EMU to be based on the all-steel Mark 3 bodyshell, departing from the "PEP"-aluminium design which had spawned the earlier Class 313 to Class 315, Class 507 and Class 508. The Mark 3 bodyshell was also the basis of Class 318, Class 455, and the diesel Class 150. The Class 317 uses overhead alternating current electrification.
The British Rail Class 375 is an electric multiple unit train that was built by Bombardier Transportation at Derby Litchurch Lane Works, from 1999 to 2005. The class form part of the Electrostar family of units, which also includes classes 357, 376, 377, 378, 379 and 387, is the most numerous type of EMU introduced since the privatisation of British Rail.
The British Rail Class 377 Electrostar is a British dual-voltage electric multiple unit passenger train (EMU) built by Bombardier Transportation on its Electrostar platform at Derby Litchurch Lane Works from 2001 to 2014.
The British Rail Class 365 Networker Express were dual-voltage electric multiple-unit passenger trains built by ABB at Holgate Road Carriage Works in 1994 and 1995 to operate services in South East England and on the Great Northern Route. These were the last trains to be built at the Holgate Road works before its closure. Due to the refurbished front end resembling a smiling face, the trains were nicknamed "Happy Trains" by enthusiasts.
The British Rail Class 319 is an electric multiple unit passenger train built by British Rail Engineering Limited's Holgate Road carriage works for use on north–south cross-London services. These dual-voltage trains are capable of operating on 25 kV 50 Hz from AC overhead wires or 750 V DC from a third rail.
The British Rail Class 376 are electric multiple unit passenger trains manufactured by Bombardier Transportation at its Derby Litchurch Lane Works. It is part of the Electrostar family, which are the most common EMUs introduced since the privatisation of British Rail. The units were ordered by Connex South Eastern, introduced in 2004/2005 by South Eastern Trains originally to replace Class 465 and Class 466 to be transferred to the Outer Suburban services to Kent to replace the Class 423 slam-door trains.
The British Rail Class 465 Networker is a class of 147 electric multiple units built by Metro-Cammell, British Rail Engineering Limited (BREL) and ABB Rail between 1991 and 1994. Originally operated by Network South East, these units are now run by Southeastern.
The Bombardier Electrostar is a family of electric multiple-unit (EMU) passenger trains manufactured by Bombardier Transportation at their Derby Litchurch Lane Works in England between 1999 and 2017. It has become the most common new EMU type in the United Kingdom since the privatisation of British Rail with a number of variants. Electrostar trains are most common on high-volume suburban commuter routes around London; and on mainline services from London south to Surrey and the south coast, east to Essex, and north to Cambridge and Stansted Airport.
The Southern Region was a region of British Railways from 1948 until 1992 when railways were re-privatised. The region ceased to be an operating unit in its own right in the 1980s. The region covered south London, southern England and the south coast, including the busy commuter belt areas of Kent, Sussex and Surrey. The region was largely based upon the former Southern Railway area.
Connex South Eastern was a train operating company in the United Kingdom owned by Connex that operated the South Eastern franchise from October 1996 until November 2003.
The Great Northern route is the name given to suburban rail services run on the southern end of Britain's East Coast Main Line and its associated branches. Services operate to or from London King's Cross and London Moorgate in London. Destinations include Hertford North, Welwyn Garden City, Stevenage, and Cambridge, and in peak hours, additional services run to Peterborough and King's Lynn. Services run through parts of Greater London, Hertfordshire, Bedfordshire, Cambridgeshire, and Norfolk.
The Thameslink Programme, originally Thameslink 2000, was a £6 billion project in south-east England to upgrade and expand the Thameslink rail network to provide new and longer trains between a wider range of stations to the north and to the south of London. The development facilitated new cross-London journeys, which means that passengers no longer have to change trains in London. Work included platform lengthening, station remodelling, new railway infrastructure, and new rolling stock. The project was originally proposed in 1991 following the successful introduction of the initial Thameslink service in 1988. After many delays, planning permission was granted in 2006 and funding was approved in October 2007. Work started in 2009 and was completed on 18 September 2020, although trains over the new routes began running in 2018.
The Networker is a family of passenger trains which operate on the UK railway system. They were built in the late 1980s and early 1990s by British Rail Engineering Limited and Metro Cammell. The trains were built for the Network SouthEast (NSE) sector of British Rail, which is where their name comes from. They are all multiple-unit trains.
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 Class 379 Bombardier Electrostar, albeit with dual-voltage capability. 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.
Network SouthEast (NSE), the sector of British Rail which ran passenger services in London and southeast England between 1986 and 1994, operated a wide variety of rolling stock during its existence. The majority of the network was electrified, and further electrification schemes took place during the 1986–1994 period; and the 7,000 vehicles owned by NSE in 1986 consisted of a mixture of electric, diesel-electric and diesel multiple units, diesel locomotives and the coaches they hauled.
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%).
