Using this HO scale train set is easy. First, make sure you have an analog DC power source. Connect the power to your railroad tracks and place the train on the tracks. Then, turn on the power and adjust the speed as you like. Since the units don't have couplers installed, use the drawbar on the F9A and the extra one in the parts bag to connect all three units together. When handling the train, be gentle as it's a fragile brass model. Avoid dropping or rough handling. For maintenance, keep it in a dry and clean place. Since the wheel wear is minimal, you don't need to worry about frequent wheel replacement. If you notice any issues with the motor noise or operation, check the power connection first. If the problem persists, you can refer to the spare parts that come with the set. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, just be aware of the return shipping policy.
