MTH: 30-21243-1 Union Pacific O Gauge RailKing ES44AC Imperial Diesel Engine With Proto-Sound 3.0 O Gauge 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.
