Using this drive system is easy. Just install it on your Athearn EMD GP50 as per the basic installation guidelines. When operating, make sure to use a DC - Analog power source as specified. Be aware that it has a moderate motor/gearbox noise, but it runs well. Since it has no lighting, don't expect that feature. For maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. If you notice any issues during operation, stop using it immediately and contact us. And remember, this model is fragile, so handle it with care during installation and storage. When shipping it back for a return, follow our packing instructions to avoid damage.
