PLEASE NOTE: When operating Walthers-branded DCC-equipped locomotives in DC mode, do not use power packs that exceed an 18V rating. This includes MRC 1300-series power packs, which have known issues with the decoders.

This Walthers Mainline EMD SD50 is perfect for heavy freight service on your HO Scale railroad. As demand for higher-horsepower units and better fuel economy continued to grow in the late 1970s, EMD began testing a new six-axle model in 1979, which entered production as the SD50 in 1981. Like the prototype, this locomotive is a great addition to your railroad's fleet of heavy diesel road units. The WalthersMainline SD50 has the features you want to make it a star performer on your layout!
