Using your HO scale brass model train Oriental Limited ATSF - Santa Fe EMD F7 Phase II set is easy. Just place it on your train track and connect the power source. The A units have operating headlights that will automatically light up when the train is powered. Remember, the set comes without couplers installed, so if you want to connect it to other trains, you'll need to add them. As for maintenance, since the wheel wear is minimal, you won't have to worry about that too much. But it's a good idea to clean the wheels occasionally with a soft, dry cloth to keep the train running smoothly. Also, keep the train in a dry place to avoid damage to the factory paint and plating. If you need to store it, use the original boxes and foam inserts for the best protection. In case you want to add the number decals, carefully follow the instructions included in the boxes. And don't forget, we offer a 30 - day no - questions - asked money - back policy if you're not satisfied with your purchase.
