2022 RailKing O Gauge ES44 Diesel Locomotives Announced

February 15, 2022 - M.T.H. Electric Trains will be releasing the RailKing O Gauge ES44 Diesel Locomotives in four select liveries in 2022. Each of these unique schemes will be available in limited production quantities and will begin shipping to M.T.H. Authorized Retailers in August 2022.

Model the ground-shaking, high horsepower drama of modern railroading with, General Electric’s Evolution Series ES44AC. At the heart of the Evolution Series is a diesel motor designed specifically to comply with new Environmental Protection Agency regulations: the turbocharged four-cycle, 12-cylinder GEVO-12. While producing the same 4400 horsepower as its 16-cylinder FDL-series predecessor, the GEVO-12 uses less fuel and spits out 40% fewer emissions. Each of its cylinders displaces 950 cubic inches, more than twice as much as an entire Corvette V-8.

GE claims the EVOs are “the most fuel-efficient, most environmentally friendly diesel locomotives in history… If every freight train in North America were pulled by an Evolution Series Locomotive, the reduction of smog-producing pollutants would be like removing 48 million cars from the road each year.” Everything about these locomotives has been examined, questioned, and re-thought, generating 25 new U.S. patents in the process. Today ES44ACs are rostered by every one of the Class 1 roads that dominate rail transportation in North America: Union Pacific, BNSF, CSX, Norfolk Southern, Kansas City Southern, Canadian National, and Canadian Pacific.

Our superbly detailed, top-of-the-line RailKing Imperial model of this modern freight mover features a full range of locomotive sounds recorded from an actual ES44AC. Outfitted with twin powerful flywheel-equipped motors, all-metal wheels and gears, and our revolutionary Proto-Speed Control, our ES44AC will haul long freights at any speed from a crawl to full throttle. Remotely activated front and rear Proto-Couplers allow you to pick up and drop off freight wherever you like. Additional Imperial features on the ES44AC include operating diesel exhaust smoke and flashing ditch lights.

Check out each of the schemes in the list on the left.
