This detailed Atlas Master Silver EMD GP20 locomotive is based on the 2000-horsepower, four-axle road switcher built for several railroads in the 1960s. A few of the GP20 carbody units are still in service in 2018, although often their interior components may have been rebuilt or upgraded. This scale EMD GP20 N Scale replica comes equipped with a replaceable lighting board and a built-in speaker to facilitate easy conversion to DCC and sound when you're ready. Other features of the EMD GP20 include a motor with dual flywheels, directional golden-white LED lighting and magnetic knuckle couplers.
