Knoxville Locomotive Works (KLW), a switcher and road-switcher OEM, was recently awarded EPA Tier 4 emissions certifications for its SE Series four- and six-axle locomotive designs.

KLW said it is “the only freight locomotive manufacturer to have achieved Tier 4 switch and line-haul certifications in this broad range of horsepower classifications with single-engine prime-movers.”

“KLW’s strategy was to assimilate a team of industry experts and supplier resources capable of advancing to the stringent requirements of Tier 4 locomotive air quality standards,” said Chairman Pete Claussen. “These locomotives use DEF at a rate of less than 2.5% per gallon of diesel fuel while delivering significantly improved fuel savings and tractive effort vs. their conventional locomotive counterparts.”
