Using this model train is easy. First, make sure the DCC address is set correctly (it's already set to 3). You can control it with a DCC controller to enjoy its sound and movement. When operating, keep it on a clean and smooth track. For maintenance, regularly check the wheels for any debris or excessive wear. Wipe the body gently with a soft cloth to keep the paint looking good. Store it in the original box when not in use to protect it from dust and damage. Remember, the inner plastic sleeve and paperwork are missing, so handle it with care. Also, if you're shipping it back for a return, make sure to follow the return policy and pay for the return shipping (unless it arrived damaged).
