My Old Triang Collection

I should imagine the Airfix kit was grafted onto a donor chassis, I think it would be quite an effort to convert the basic plastic wheels in the kit to make them suitable for running on an electrified track as for a start they would be plastic in the kit

As already pointed out the bars on the window of the carriage indicate a guards compartment that would sometimes also carry parcels, mail and precious goods. That particular carriage would be referred to as a 'composite brake coach', whereas the others are full blown passenger carriages with compartments and a corridor connecting them on one side. That is apart from the top carriage in the two pictures, the first picture top carriage is a buffet car, the top carriage in the 2nd picture is a full mail/brake car.

You got a nice selection there Chris, although I notice there is a conspicuous lack of pacifics such as an A1/A3, A4, Duchess/Princess/Coronation class or alternatively a castle, hall or similar. Out of interest is the full baggage car a kit as well? I just wondered as it looks like the glazing has slipped a bit.
