This detailed Atlas HO Scale Master Silver GE Dash 8-40BWH is based on the four-axle diesels delivered to a Amtrak. In 1991 Amtrak, faced with a motive power shortage, turned to GE for an order of 20 Dash 8-32BWH locomotives. This unique model was basically a Dash 8-32B locomotive equipped with a North American Cab and built on the longer Dash 8-40BW frame. Some additional modifications for passenger service were included. A total of 20 units were built and they are still in Amtrak service in the 2020s. This detailed model features a five-pole, skew-wound motor with dual flywheels, directional LED lighting, working front and/or rear ditch lights as appropriate, Accumate(R) magnetic knuckle couplers, accurate decoration and other roadname-appropriate body details. This model also includes a DCC socket for easy decoder installation when you're ready.
