Using this dynamometer car is straightforward. Just place it on your model train track and let it be part of your train setup. When handling it, be gentle as it's a fragile item. To keep it in good condition, store it in the original box and foam when not in use. Avoid exposing it to excessive moisture or direct sunlight which could cause tarnishing. If you notice any dirt, you can use a soft, dry cloth to gently wipe it clean. Remember, this model is long out of production, so take good care of it to enjoy it for a long time.
