Using this model is easy. Just connect it to a DC - analog power source and it'll start running smoothly. Remember, since it has no lighting, you won't have that feature. When handling, be gentle as the model is fragile, especially since it's made of brass. For maintenance, regularly check the wheels for any excessive wear. You can clean the mild tarnish on the unpainted surface gently with a soft cloth. Keep it in the original box and foam when not in use to protect it. If you're shipping it back for a return, make sure to pack it well to avoid any damage. And always use approved payment methods as mentioned to ensure a smooth transaction.
