Powering freight’s destination to zero

Cummins Inc. and Knoxville Locomotive Works, Inc. have announced the next step in Tier 4 locomotive repower programs


Building on successful sales of KLW EPA Tier 4 certified and CARB verified locomotives across the US, KLW has recently completed the remanufacture of an existing line-haul freight locomotive utilizing the Cummins 4,400 horsepower Tier 4 certified QSK95 engine system. The locomotive also employs a CAF Power & Automation AC traction system along with components from other rail industry suppliers.

“We are excited to showcase our clean diesel technology in freight locomotives,” said Regina Barringer, Cummins Global General Manager, Rail and Defense. “Many rail operators have committed to reach net zero emissions and we are confident that the QSK95 will play an important role to helping rail operators improve the emissions for both their current and future line up of locomotives.”

The KLWX 4400 ACT4 locomotive is currently running on Canadian National Railway where it is undergoing reliability growth testing.
