How to disassemble a locomotive without damaging it and then reassembling it is one of the more advanced tasks of a model railroader.
Some people just want to see the inside of the locomotive, while more often, there’s a circuit board that needs repair or replacement, gears that need lubricating, or a faulty wire or light of some kind.
Whatever the reason you might need to know how to disassemble a locomotive, the process builds on other modeling skills: steady hands, organization, proper techniques, and most of all, patience.
In this video, experienced local model railroader Keith Schmidt takes apart an HO scale SD50 locomotive made by Walthers and reassembles it in good working order.
