IN: Cummins QSK19-R to Power Nippon Sharyo DMU Train Designed for New Transit Routes in North America

Cummins Inc. announced April 25 that the Tier 4 Final-compliant QSK19-R railcar engine will power the new Nippon Sharyo Diesel Multiple Unit (DMU) train designed for transit and commuter services in North America.

Contracts have been awarded to Nippon Sharyo U.S.A./Sumitomo Corp. of America for 32 railcars, configured as either two- or three-car DMU sets with the 760 hp (567 kW)-rated engine installed underfloor in each railcar.

The QSK19-R is the first railcar engine being produced in North America that is certified to meet Tier 4 Final ultra-low emissions standards set by the U.S. Environmental Protection Agency (EPA), taking effect Jan. 1, 2015. The underfloor QSK19-R is the latest generation of the 19-liter, 6-cylinder engine manufactured at the Cummins Seymour, Ind. engine plant.

To meet Tier 4 Final regulations and the equivalent Stage IIIB standards for railcars in Europe, the 19- liter engine is fully integrated with Cummins Selective Catalytic Reduction (SCR) aftertreatment. The SCR system reduces exhaust emissions to extremely low levels from the new DMU, with the three-car, three-engine configuration totaling 2280 hp (1700 kW) output.

"We are delighted to be working with Nippon Sharyo to power its new DMU, which is uniquely designed for North America and will offer a fast, clean and energy-efficient travel alternative to heavily congested highways," said Ed Pence, vice president and general manager - Cummins High- Horsepower Engine Business.

"Production of the QSK19 engine is now underway at our Seymour facility, which means we will see the new Nippon Sharyo DMU up and running this year, ahead of when the Tier 4 Final regulations take effect," added Pence.

The first Nippon Sharyo DMU is scheduled for delivery in 2014 for the air-rail link currently under construction from downtown Toronto to the Toronto Pearson International Airport, connecting the two busiest transportation hubs in Canada with a fleet of 18 railcars to be operated by GO Transit. Another 14 railcars will be delivered to the Sonoma-Marin Area Rail Transit (SMART) rail line, north of the San Francisco Bay, running on a new line currently under construction.
