Description
With a wave of industry consolidation behind it, North American railroading has entered a modern era of heavy hauling. Freight traffic is booming, and locomotive orders from the continent's dominant Class I roads—Union Pacific, BNSF, CSX, Norfolk Southern, Canadian National, and Canadian Pacific—are moving at a record pace. The battle to supply this 21st-century fleet is fiercely contested by the two remaining diesel titans: Caterpillar®-owned EMD with its SD70ACe, and General Electric with its standard-bearing Evolution Series, the ES44AC and ES44DC.
At the heart of the Evolution Series is a revolutionary prime mover: the four-cycle, 12-cylinder GEVO-12. Delivering the same massive 4,400 horsepower as its 16-cylinder FDL predecessor, the GEVO-12 consumes less fuel and reduces emissions by a staggering 40%. GE has boldly proclaimed the EVOs to be “the most fuel-efficient, most environmentally friendly diesel locomotives in history.” Re-thought from the ground up and backed by 25 new U.S. patents, every major Class I railroad has eagerly adopted them, with BNSF currently rostering the largest fleet.
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.
