How to use: This sleeper car is a great addition to your model train set. You can place it on tracks suitable for HO scale trains, like those used for the North Coast Limited or the Mainstreeter. It doesn't come with couplers, so you'll need to add them if you want to connect it to other cars. Just follow the instructions in the parts bag for installing the couplers using the included screws. Attention: Be careful when handling the car, as it's made of brass and can be a bit fragile. Also, since it's an older model, it might have some minor tarnish, but that's normal. Maintenance: To keep it in good condition, store it in a dry place. You can gently clean it with a soft cloth to remove any dust. If you notice more tarnish over time, you can use a mild brass cleaner, but be sure to test it on a small, hidden area first.
