Hi Ray, Saw this layout of yours at the Taunton School exhibition a few years ago. Love it! Feltham was the nearest shed to me when I lived in Twickenham and managed to bunk a few times. I remember you have a model of a W class, built from a PDK kit I think. I am thinking of getting the kit. What motor did you use? PDK themselves recommend High Level motors and gears but have not a clue as to which to use??
