Using this passenger train set is easy. Just place the cars on the tracks and let them roll. If you want to use the aftermarket lighting in some cars, you can connect the power source, but remember it's untested. When handling the set, be gentle as the brass parts are fragile. Store the set in a dry and clean place to avoid damage. If the cars get dirty, you can use a soft cloth to gently wipe them. If you have the original boxes, it's a good idea to store the cars in them for better protection. And don't forget, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, just pay for the return shipping unless the item arrives damaged.
