Using your O scale model train is easy. First, make sure it's on a clean and well - set track. Connect it to a DC Analog power source. The operating headlight will turn on once the power is on, giving a nice touch to your display. When running it, you'll notice it's very quiet, so it won't be a distraction. As for maintenance, regularly check the wheels for any signs of wear. Since it has minimal wheel wear currently, keeping it clean will help maintain that. You can use a soft, dry cloth to wipe the exterior of the train and the interior details. For the couplers, ensure they are clean and functioning properly so that the train cars can connect smoothly. When not in use, store it in the original box and foam to protect it from damage.
