This detailed AtlasO Premier GE ES44AC is based on 4,400-horsepower road diesels introduced in the 2000s and operated by a number of railroads. It comes equipped with ProtoSound 3 and DCS for command control operation on DCC 2-rail O Scale layouts. The ES44AC offers a combination of detail, realism, and performance. Listen to the chant of an authentic GEVO-12 motor, and throttle down as low as three scale miles per hour so you can admire the details as the Evolution Series ES44 glides by: see-through fans and grilles, walkways with safety tread, and a host of other separately applied metal details, plus a full LED lighting package. This GE ES44AC is ready to run on your 2-rail O Gauge railroad. The ES44AC is one of many AtlasO locomotives.
