It has see-through radiator fans and cab windows, DCC-ready with Quick Plug™, an improved motor, and wheels that work on popular tracks.

Using this Athearn RS-3 locomotive is a breeze. Just place it on your HO scale track and connect the DCC system if you want to take advantage of the advanced features. If you're using DC, the engine, horn, and bell sounds will still work, but some functions may be limited. When operating, make sure the track is clean to ensure smooth movement. For maintenance, gently clean the wheels and electrical contacts regularly to keep the current flowing well. Store the locomotive in its interior plastic blister to protect it. Avoid exposing it to extreme temperatures or moisture. With proper care, this locomotive will provide you with many hours of enjoyable model railroading.
