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 standards. 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.
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.
The DMU is offered in three variants that shared the same mechanical design:
The Sonoma Marin Area Rail Transit (SMART) ordered 14 cars in December 2010. Half of the cars were ordered as A-car and the remaining as B-car.
In June 2015 SMART received a grant from California State Transportation Agency (CalSTA) to purchase 3 C-cars. These would have allowed SMART to use 3 train sets with a third car in the middle. In April 2016, SMART's general manager negotiated with CalSTA and Nippon Sharyo to adjust the order so SMART will receive 2 more full train sets bringing their fleet size to the required 9 (18 cars) needed for service to Cloverdale.
