Using this HO scale brass rail truck with trailer is quite straightforward. Just connect it to an appropriate analog DC power source. However, keep in mind that because of its limited electrical pickup, it may not work well on unpowered frogs or imperfect tracks. When handling the model, be gentle as it's a fragile item, especially being made of brass. For maintenance, you can clean the model gently to remove any dust or dirt. If you notice the significant motor/gearbox noise getting worse, it might be a good idea to have it checked. Also, store it in its original box and inserts when not in use to protect it from damage. And remember, if you're not satisfied with your purchase, you have a 30 - day no - questions - asked money - back policy, though you'll be responsible for return shipping unless the item arrives damaged.
