The British Rail Class 302 (pre-TOPS AM2) was a type of electric multiple unit (EMU) introduced between 1958 - 1960 for outer suburban passenger services on the London, Tilbury and Southend Railway route. This class of multiple unit was constructed using the Mark 1 bodyshell and was slam door. ==Service History== Each unit was formed of four coaches in the formation BDTS - MBS - TC - DTS. The initial set numbers were 201-312, later prefixed by the class number 302. They were among the first 25 kV units delivered to the Eastern Region, and although ordered for the LT&S electrification, which route they were long associated with, they were used initially on the Liverpool Street to Southend Victoria line from the day this was converted from DC to AC power, covering the period while the former DC units were rebuilt to AC. The first 20 units remained on the GE main line for the bulk of their lives, with the remainder operating on the LT&S from Fenchurch Street from 1962. Like all the Eastern Region AC EMUs of the period, they were equipped to operate on both 25 kV AC and the reduced 6.25 kV voltage in the inner London areas where headroom for the overhead wires was reduced. On the LT&S the changeover point was just east of Barking station on both Upminster and Tilbury routes. Trailer coaches were originally fitted with Gresley bogies which were replaced on Driving Trailer (DT) and Trailer Standard Open (TSO) which was formerly Composite Trailer and B5 Bogies on Battery Driving Trailer which became Battery Composite Trailer, the refurbishment moved First class accommodation to a position over the Westinghouse CM38 main compressor which was noisy and caused vibration. The Motor Coach retained its Gresley derived bogies after refurbishment. The Battery Driving Trailer and Driving Trailer were fitted with drop head buckeye couplers with screw coupler in the Guards Van, retractable Buffers are also fitted only on outer ends of the Battery Driving Trailer/Driving Trailer. Originally the vehicles were insulated with "blue" asbestos which was removed and sealed during refurbishments. Unit 302 244 was involved in an accident with a lorry at a level crossing at Low Street railway station in Tilbury, after which it was decided to scrap the leading carriage. This was replaced with a carriage originally belonging to a Manchester-Bury Line Class 504. Following the privatisation of British Rail, the units passed to LTS Rail in 1996. The class was fully withdrawn from service in 1999 due to the age of the units, with some being 40 years old. They were replaced by Class 310 units, Class 312 units, and Class 317 units, the latter of which were on loan from WAGN. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British Rail Class 302」の詳細全文を読む スポンサード リンク
