Using this set is easy. You can display it in your model train collection to add a touch of history as these cars were used on the '400' passenger trains. When handling the set, be gentle since the cars are made of brass and can be fragile. Avoid dropping or applying too much pressure on the cars or their parts. For maintenance, use a soft, dry cloth to dust the cars regularly. If there are any stubborn marks, you can use a very mild cleaner on a small, hidden area first to test it. Keep the set away from extreme temperatures and humidity to prevent damage to the paint and the metal parts. When storing, place it back in the original box and foam to protect it. Enjoy your unique model train set!
