It seems that there was a problem in sourcing certain platform buildings in the farish Art Deco range. Simon Dawson (Recreation21) has produced a range of such buildings compatible with the farish range, although with a variety of differences including a buffet, a new station building and a lot of mix and match waiting rooms and toilets etc.they are available through shapeways and compare favourably in price with the farish limited range.
