This is a generic set of parts put together from the existing parts line,to replace the molded floor piece that comes on the Golden Gate depot streamline series
of cars. This will allow you to have better looking and more accurate types of models, and does away with the toy train look. The floor piece is .040" thick styrene with all the mounting holes and an opening for the light switch as well. You will have to mount the new parts to the floor and paint as required .
