Cummins Inc. has received Tier 4 Locomotive certification for its QSK95, making it the first single prime power engine certified by the U.S. Environmental Protection Agency (EPA), the company announced April 4, 2016.

At 4,400 hp (3,281 kW), the QSK95 achieves the highest output of any 16-cylinder high-speed diesel, and is capable of a top speed of 125 mph (201 km/hr) as a prime mover. Combining Cummins latest-generation Modular Common Rail Fuel System (MCRS) with quad-turbocharging, the QSK95 delivers reduced noise and excellent response in a smaller footprint than that of medium-speed diesels traditionally used in locomotives. Integrated Selective Catalytic Reduction (SCR) after treatment makes the QSK95 capable of achieving the ultra-low- emissions required at Tier 4.

The QSK95 powers Siemens(R) Charger locomotive—a diesel-electric passenger locomotive that will be put into service by the Departments of Transportation in Illinois, California, Maryland and Washington which will operate in additional states including Michigan, Missouri, Wisconsin, Iowa and Oregon, as well as Brightline, (TM) the privately owned and operated passenger rail service that will connect Miami and Orlando.

“We’re pleased to have reached this milestone,” said Jim Trueblood, Vice President – High-Horsepower Engine Program. “ Cummins is committed to bringing clean, efficient, durable engines to every market we serve. This certification for the QSK95 for locomotives delivers on that commitment for our customers in the rail industry.”

The QSK95 joins Cummins industry-leading lineup of Tier 4-certified product for rail applications, including the QSB6.7 (140 hp to 300 hp/104-224 kW), the QSX15 (600 hp/447 kW), the QSK19-R (760 hp/567 kW) and the QSK60 (2310 hp and 2700 hp/1723 and 2013 kW).
