KNOXVILLE, Tenn. — Knoxville Locomotive Works, an original equipment manufacturer of switcher and road-switcher locomotives, was recently awarded EPA Tier 4 emission certifications for its SE Series four- and six-axle locomotive designs. The Tier 4 certifications include the switch duty cycle for KLW models rated at 2,000, 2,200 and 2,300 brake horsepower and the line haul duty cycle for Knoxville models rated at 2,400 through 3,200 brake horsepower. Knoxville 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. These locomotives use [diesel exhaust fluid] at a rate of less than 2.5-percent per gallon of diesel fuel while delivering significantly improved fuel savings and tractive effort versus their conventional locomotive counterparts,” says Knoxville Locomotive Works’ Chairman Pete Claussen.
More information is available online.

The article states that Knoxville is an original equipment manufacturer. That brand new stuff. So why does this locomotive look exactly like a 50 year old EMD? Or does OEM refer only to the prime mover, and everything else is a rebuild?
Good for them.Take note Muncie
YVRR 3200. I operated that thing earlier today.
Mr. Berg,
Why wouldn’t a railroad want locomotives that use less fuel and have more tractive effort?????
Last I heard, the class I railroads didn’t want to use Diesel Exhaust Fluid. Regional railroads and short lines might be interested though.
Tier 4 brings NOx and particulate emissions to very low levels. I think the next push will be for less carbon dioxide emissions, which will require burning less fuel or some kind of carbon capture system. Moving to natural gas might also reduce carbon dioxide emissions.
Won’t matter. Start ramping up for Tier 5 then Tier 6 then Tier……………It will never end.
If someone explained this emissions thing imposed on america’s railroads to the POTUS Donald Trump, he might just get ’em canceled. He’s working on getting some things eased a little bit.
