I am converting a Bachmann 2-truck Shay to Dead Rail operation. When I opened it up, it is full of electronics for DCC, lights, sound, smoke, and maybe other things. In order to install the radio receiver, controller, and sound board, I'll need to remove the other things. And maybe there is something in there that I can use. I really need a drawing or two to make the dismantling more efficient. Does anyone know where I can get such a thing?
