Using this train control system is easy. First, make sure you have a 21 - pin decoder like EU621 or WOW121, as the system won't work without it. Then, replace the original lighting board in your Bachmann steam engine, like the 4 - 6 - 0, with this motherboard. If you pair it with a WOW121, you'll get great sound and smooth performance. When using it on the tracks, the KA3 Keep Alive® helps it run smoothly even on troublesome parts. For maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. If you have any problems, check the connections and make sure the decoder is working properly.
