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.[4]
Design
Each Nippon Sharyo DMU is powered by one Cummins QSK19-R[3] 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.[5]
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.

Sonoma Marin Area Rail Transit
The Sonoma Marin Area Rail Transit (SMART) ordered 14 cars in December 2010.[6] 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.[7] 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.[8]
The first cars, numbered 101 and 102, were delivered to SMART in April 2015. The final cars from the original order, numbered 113 and 114, arrived in December 2015.
Union Pearson Express
Seven trains comprise the fleet of Union Pearson Express (UP Express), grouped into 4 three-car and 3 two-car train sets (for a total of 18 cars).[4] Union Pearson Express units feature enclosed overhead luggage bins as required by Transport Canada, and an enhanced enclosed luggage tower.
The first cars were delivered to UP Express in August 2014. All 18 cars ordered were delivered and entered service by June 2015.
Proposed
TriMet considered ordering a two-car train for its Westside Express Service to supplement its fleet of Colorado Railcar DMUs. MBTA also purchased an 18-car option from SMART for its proposed Indigo Line service.[9]
Incidents and accidents
A July 2016 fire aboard one of Toronto's units revealed a fatal design flaw in the Cummins engine's crankshaft. This delayed the beginning of SMART revenue service until their engines could be serviced to correct the problem.[10]
