The British Rail Class 322 electric multiple units were built by BREL in 1990〔(【引用サイトリンク】 Class 322 Technical data )〕 for the dedicated Stansted Express service from London Liverpool Street to Stansted Airport. After becoming surplus to requirements on this route, the fleet saw short periods of use on various different routes around the country. The fleet is currently operated by Northern Rail and can be seen working services around the Leeds area. ==Description== In 1987, British Rail (BR) was extending the electrification north from London Liverpool Street towards Cambridge. Included in this plan was the construction of new branch line, diverging from the mainline at Stansted Mountfitchet, to serve the newly built , which opened in 1991. Therefore, BR decided to build a dedicated fleet of units to work the new Stansted Express service. To reduce costs, the Class 322 units were built to the same design as the successful Class 321 units, which were still under construction for services on the GEML and WCML. Despite the Stansted route falling under the jurisdiction of Network SouthEast (NSE), the units were delivered into service in a special white livery with a broad green band, instead of the more usual NSE blue/red/white livery. The units are fitted with Tightlock couplers. This allows them to work in multiple with , , , , and units, as well as units of the same class. Five 4-car units were built, numbered 322481-485. Each unit consisted of two outer driving trailers, an intermediate trailer, and an intermediate motor. The technical description of the formation of each unit is DTCO+TSO+MSO+DTSO. Individual vehicles are numbered as follows: *78163-78167 - DTCO *72023-72027 - TSO *63137-63141 - MSO *77985-77989 - DTSO The units were also the last of a long line of BR multiple units to be based on the Mark 3 bodyshell design. 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 322」の詳細全文を読む スポンサード リンク
