The Class 170 "Turbostar" is a British diesel multiple-unit (DMU) train built by Bombardier Transportation (and previously ADtranz) at its Derby Litchurch Lane Works. Introduced after privatisation, these trains have operated regional as well as long-distance services, and to a lesser extent suburban services. 122 units have been built. ==Design== The class is a development of the design used in the British Rail Class 165 and 166 DMUs known as the ''Networker Turbos'' which were built by BREL and later ABB Transportation Ltd before that company became part of Bombardier. Notable features shared are the aluminium alloy frame and Voith transmission as well as the general body shape (the cab ends are similar to those of the Class 168, but not Class 165/166), interior design and door fittings. The final drive is sourced from ZF instead of Gmeinder and the diesel-engine supplier changed to MTU.〔(TURBOSTAR – United Kingdom bombardier.com )〕 The engine and transmission are under the body; one bogie per coach is powered, the other unpowered. All coaches in the set are powered (there are no unpowered trailers). The units can work in multiple with trains in the 15X series, i.e. ''Sprinters'', and with other units of the same class. They are unable to operate in multiple with units in the 16X series due to different wiring arrangements.〔(CLASS 170 'Turbostar' therailwaycentre.com )〕 Seating arrangements are of both 2+1 (first class) and 2+2 (standard class) formation, and give a seated passenger capacity of between ~100 and ~200 per three-car set (depending on the specifications of the operator).〔(TURBOSTAR – United Kingdom – technical data – bombardier.com )〕 2-car sets are also operated. 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 170」の詳細全文を読む スポンサード リンク
