N Scale London Underground 1938 Stock

Despite not modelling in N, the idea came into my head the other day to have a go at building a train of 1938 tube stock in that scale, pretty much just to see if it is possible. So far I have assembled two sides and the roof of a driving motor car. The roof uses two layers of 0.5mm styrene, with cut outs in the top layer to represent the doors, over several formers for the curved shape on a 1mm base layer to give it strength. For the sides I have used a base of 0.5mm transparent styrene, which forms the glazing and the "front" layer of the doors, with the bodysides and window frame detail built up on the front of it, and the recessed door panels and door glazing layer behind it.
I'm not sure at this stage if the whole thing will actually work, at so far I'm mainly testing my ability to build something this small and fiddly. If I can get one carriage done I'll order a Kato Portram to provide motor bogies and press on with the others.
