Production Underway Of 760 HP Underfloor Railcar Engines At Cummins Seymour Plant Ready To Meet Tier 4 Final Ultra-Low Emissions

COLUMBUS, Ind. (April 25, 2014) – Cummins Inc. (NYSE: CMI) today announced 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.

In addition to the clean-engine credentials, the QSK19-R has very fast torque response, with a peak output of 2275 lb-ft (3084 N•m). This allows the DMU to achieve rapid acceleration from idle – an important advantage in reducing journey times on routes with short distances between stations.

Smart electronic controls and advanced combustion techniques result in a remarkably smooth power delivery from the QSK19-R, providing a comfortable travel experience for passengers when the DMU runs at its top speed of 90 mph (145 kph). The engine runs quietly with minimal vibration, due to an upgraded common-rail fuel system able to precisely balance fueling across the six cylinders.

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.  
Compact Underfloor Power
The horizontal envelope of the QSK19-R allows for a highly compact installation within a self-contained power module positioned underneath the railcar body. This space-efficient installation enables a flexible seated capacity of 180 to 237 passengers for the three-car DMU train set, together with additional space for standing passengers during busy periods. Passenger convenience is further enhanced with step-in level boarding from the platform and allocated space in each railcar for up to 12 bicycles, wheelchairs or strollers.   

On-board power such as air-conditioning is generated from the QSK19-R by means of a high-efficiency drive shaft, eliminating the need for an additional engine for hotel power.
Proven Track Record For DMUs
The QSK19-R already comes with an enviable reputation for uptime reliability well proven in DMU intercity operations in Germany, the United Kingdom, Australia and China. A population of more than 1,700 railcars powered by the QSK19-R makes this by far the most successful underfloor railcar engine in the industry.

Although compact in size, the QSK19-R shares the same inherent structural strength of larger Cummins high-horsepower engines, and uses premium materials throughout the engine to enhance durability. As a result, the engine is capable of operating for up to 20,000 hours before a rebuild may be required, dependent on duty cycle. Multiple-life capability means that the QSK19-R engine continues to work at peak performance even after three rebuilds.
