Using your Union Pacific EMD GP30B Cabless model is easy. Just connect it to an analog - DC power source and watch it go. Remember, it runs well but can be a bit noisy. When handling the model, do it gently as it's a fragile item. For maintenance, check the wheels regularly for any signs of excessive wear. If you notice any issues with the motor or gearbox noise, you can contact us for advice. Keep the model clean and store it in the original box and foam when not in use to protect it from damage. Also, be aware that if you're shipping it back for a return, you'll be responsible for the shipping costs unless the item arrived damaged.
