I know the one you're talking about and I've seen the prices, but I am certain that the loco was on n gauge track.

I do remember that it was a kato chassis but I don't for the life of me remember what it was

Hey guys, just caught the bug of modelling after a long time keeping my trains away... I have found my old culdee toy and I watched an old topkazz fat video in which he converted the toy to a model. Now my question is what chassis did he use to make it?
