Digihat Conversion

This conversion follows the Graham Farish insulating bush (Digihat) method to isolate the lower motor connection from the chassis. The chassis is quite compact, and there isn't much room inside the body, but if you use one of the very small decoders, it will just fit inside the roof area at the back. If you don't mind being able to see the decoder in the cab, there is plenty of room for it there too.
