Using this Athearn HO scale model train is easy. First, make sure your track meets the minimum 18 - inch radius, though a 22 - inch radius is recommended. Connect the model to your DCC or DC power system. For DCC, you can access full functions and program multiple unit lashups. In DC, basic engine, horn, and bell sounds work. When storing, use the secure packaging to keep the model safe. For maintenance, regularly clean the wheels and electrical pickups to ensure good current flow. Avoid exposing the model to extreme temperatures or humidity. If you want to adjust functions, refer to the CV chart included in the box.
