This is a Master Class at card modelling. I have a station building to remodel (wrong windows!) so I'm looking for tips!
Great stuff.
By the way, @Galteemore will tell you who to go to to get a 4mm scale model of the late Mac Arnold, Whitehead's other famous resident. The first was, of course, Harold Houston, designer of the B&L corridor coaches and the magnificent North Atlantic Express coaches. They'd make a nice pair for the platform!
