Although a GWR fan I too have a soft spot, they were around Crewe Works etc into the 1960s and I remember the Triang Models being featured on Berrow, to my mind possibly one of the most satisfying layouts (not sure about the turntable feature being added etc), a Branch off a Branch. I have only ever owned 2 models (a 7mm scale one from a JM Products kit, sold years ago and a Hornby blue S&D one, still in the box).
