The Nippon Sharyo DMU is a model of diesel multiple unit passenger train designed and manufactured by Nippon Sharyo for the North American market, and compliant with FRA Tier 1 crash worthiness standard. It has been ordered by Sonoma-Marin Area Rail Transit (SMART) in Sonoma and Marin Counties, California, and by Metrolinx for the Union Pearson Express airport link in Toronto, Ontario. The vehicles are designed to be convertible to electric multiple unit operation.〔(【引用サイトリンク】accessdate=2014-06-05 )〕 ==Design== Each Nippon Sharyo DMU is powered by one Cummins QSK19-R〔 diesel engine with hydraulic transmission and regenerative braking, and meets US EPA Tier 4 emission standards. Structurally each DMU is FRA Tier 1 compliant with crash energy management features, making it capable of operating on the same line with standard North American freight trains without the need of special waivers. Braking energy is converted into electricity by the auxiliary power generator, and helps to provide on-board lighting and heating.〔(【引用サイトリンク】title=SMART Technical Specification for Diesel Multiple Units )〕 The DMU is offered in three variants that shared the same mechanical design: *A-car: one aerodynamic gangway-less end with full-width cab, one flat non-cab end with gangway, equipped with one ADA-compliant bathroom *B-car: similar to A-car but with service bar instead of bathroom *C-car: similar to A-car but the aerodynamic end was replaced with a flat end with gangway and cab, so it can be run either as middle car or end car of a train. 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「Nippon Sharyo DMU」の詳細全文を読む スポンサード リンク
