The British Rail Class 307 electric multiple units were built by BR at Eastleigh Works from 1954-1956. They were initially classified as AM7 before the introduction of TOPS.
British Rail Class 309
The British Rail Class 309 "Clacton Express" electric multiple units (EMUs) were built by British Rail (BR) York Works from 1962-1963. They were initially classified as Class AM9 before the introduction of TOPS. These units were the first express 25 kV alternating current (AC) units to be built by British Rail, and British Rail's first EMUs to be capable of 100 mph.
British Rail Class 308
The British Rail (BR) Class 308 alternating current (AC) electric multiple units (EMU) were built by BR at York, in three batches, from 1961–62. They were initially classified as AM8 units before the introduction of TOPS.
British Rail Class 310
The British Rail (BR) Class 310 is a slam-door, alternating current (AC) electric multiple unit (EMU) introduced in 1966 as part of the West Coast Main Line electrification project. They were initially classified as Class AM10 units before the introduction on the TOPS classification system. Constructed at BR's Derby Carriage and Wagon Works. They consisted of four carriages - a second class driving trailer, a second class trailer, a second class motor car (with guard's/luggage compartment above which the pantograph was mounted) and a composite (1st and 2nd class) driving trailer. The maximum speed was 75 miles per hour. A glass partition behind the driver's cab enabled passengers in the leading and rear coaches to have an excellent view of the line ahead or behind.
British Rail Class 311
The British Rail Class 311 alternating current (AC) electric multiple units (EMU) were built by Cravens at Sheffield in 1967. They were intended for use on the line from Glasgow Central to Gourock and Wemyss Bay, which was electrified in 1967.
British Rail Class 312
The British Rail Class 312 is a type of alternating current (AC) electric multiple unit (EMU) built in 1966-1974 intended for use on outer-suburban passenger services. It was the last class of multiple unit to be constructed to the British Rail Mark 2 bodyshell, and also the last with slam doors. This latter feature contributed to their relatively early withdrawal (between 25–28 years old, compared to a life expectancy of 30 years). Ironically, the examples withdrawn by First Great Eastern and later 'one' Great Eastern between 2003 and 2004 were slightly newer than most of the carriages the operator is introducing during 2005 for use on its premier express service.
British Rail Class 314
British Rail Class 314 alternating current (AC) electric multiple units (EMU) were built by BREL at York works from 1978 to 1979. They were the second variety of British Rail's then-standard 1972 design for suburban EMUs, which eventually encompassed 755 vehicles and five Classes (Class 313/314/315/507/508). Able to operate from 25 kV overhead line current collection only, the fleet worked outer-suburban services on the Strathclyde Passenger Transport rail network in Central Scotland.
British Rail Class 315
British Rail Class 315 alternating current (AC) electric multiple units (EMU) were built by BREL at York works from 1980 to 1981. They were the fifth and final variety of British Rail's then-standard 1972 design for suburban EMUs, which eventually encompassed 755 vehicles and five Classes (Class 313/314/315/507/508). Like the Glasgow-based Class 314 units, they are only able to operate from 25 kV overhead line current collection. The fleet works inner-suburban services on the Great Eastern Main Line run by the train operating company TfL Rail out of London Liverpool Street. Class 315s also work services from Liverpool Street to Chingford, Enfield Town and Cheshunt operated by London Overground.
British Rail Classes 316 and 457
Class 316 and Class 457 were two suggested TOPS classifications. They were given to a single electric multiple unit (EMU) at different stages of its use as a prototype for the Networker series.
British Rail Class 317
The British Rail Class 317 electric multiple units were built by BREL at York Works in two batches, from 1981-82 and 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. The Mark 3 bodyshell was also the basis of Class 318, Class 455, and the diesel "sprinters" pioneered by the Class 150.
Nehebkau
In Egyptian mythology, Nehebkau (also spelled Nehebu-Kau, and Neheb Ka) guarded the entrance to Duat, the Egyptian underworld. He was made up of Ka and Ba, the two parts of the soul. He is pictured as a snake with two heads. Atum was said to have to keep his finger on Nehebkau to keep him from being out of control. Since he was a snake, he was believed to heal those bitten by snakes and/or scorpions.
British Rail Class 318
The British Rail Class 318 is an electric multiple unit (EMU) train, which operates exclusively in the Strathclyde Partnership for Transport network in West Central Scotland. The units were introduced fully on 29 September 1986 as part of the electrification of the Ayrshire Coast Line between Glasgow Central and Ayr/Ardrossan with alternating current (AC) overhead lines. Usage was extended to Largs in January 1987. They were also used on the Inverclyde Line in small numbers and on rare occasions the Cathcart Circle Lines (including to Neilston and Newton).
Ka
Ka is one of the five parts of the Egyptian idea of the soul. The Ka was the life force and left the body during death. Ka was believed to be in food and drink and was placed with the dead for offerings. The Egyptians believed that at death the Ba and the Ka join together through Nehebkau before entering Duat.
British Rail Class 319
The British Rail Class 319 dual-voltage electric multiple units (EMU) were built by BREL York in two batches from 1987–88 and 1990. The trains were introduced for new north-south cross-London services from Bedford to Brighton, and since privatisation these services have been operated by Thameslink and First Capital Connect, the former franchise having been merged with the Great Northern section of the former WAGN franchise to form the latter train operating company at 0200 BST on 1 April 2006 as a result of re-franchising. Class 319 units have dual power pick-up, from either 25 kV alternating current (AC) overhead lines for services north of London, or 750 V direct current (DC) third rail to the south. However, some units were only used on outer suburban services in South London. The Class 325 postal units were based on the Class 319 units, with the same traction equipment and body design, but are fitted with cabs of the same design as the newer Class 365 and Class 465
"Networker" units.
Since delivery of new rolling stock for Thameslink services started in 2015, a number of Class 319 units have been redeployed for use on other operators' services, including in the North West of England. In 2017, the last Thameslink units were withdrawn and were replaced by Class 700s.
British Rail Class 320
The British Rail Class 320 is an alternating current (AC) electric multiple unit (EMU) train found on the Strathclyde Partnership for Transport (SPT) rail network in Central Scotland, and is used exclusively on the North Clyde Line between Helensburgh and Airdrie, North Lanarkshire via Glasgow Queen Street railway station.
