The British Rail Class 456 electric multiple-unit trains were built by BREL York Works from 1990-91. == Description == 24 two-car units were built as direct replacements for the elderly Class 416 2EPB units which operated on the Central Division of the Southern Region of British Rail.〔(Class 456 ) - Southern E-Group. Retrieved 18 December 2010.〕 Units were delivered into traffic painted in Network SouthEast blue, red and white livery. Units were numbered in the range 456001-024. Each unit consisted of two carriages; a driving motor and a driving trailer.〔 The technical description (when new) of the unit formation is DMSO+DTSOL. Individual carriage numbers were as follows: *64735-64758 - DMSO *78250-78273 - DTSOL When first introduced, the units suffered from many technical and reliability problems, which delayed the replacement of the 2EPB units. However, once they settled down the units were used on many services, including London Bridge to London Victoria via Crystal Palace, and via Denmark Hill and London Victoria to Horsham. Before the lines closed in 1997 to allow the building of Tramlink, Class 456 units worked services on the West Croydon to Wimbledon Line before being allocated to Victoria - Epsom via Sutton and West Croydon, especially at peak times, as well as services from Epsom Downs and Dorking. The trains then moved to South West Trains, being part of a 455+456+456 set to cover for the refresh of the company's Class 455 sets, before moving to a ten car 455+455+456 set. 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 456」の詳細全文を読む スポンサード リンク
