Seeing that the brand Graham Farish is being talked about on another thread there was something I wanted to share about these locos. I have two chassis that I run and noticed that in all the years I've had them I've never cleaned the wheels !! All my other locos require regular cleaning. Obviously a different type of metal. Or, did I just get lucky ?

Despite both being 0-6-0's they never stall

Anybody else had this experience with Graham Farish ?
