I received my carriages to go with the A3 loco, here's some pictures of one of them. This one is a 'Brake corridor composite' carriage, this is a mixed class carriage with 1st and 3rd class compartments. Note that they have even gone to the effort of making the seats in the respective compartments different colours to reflect how the real ones would have been. I did put a ruler in there for reference on the 3rd picture, but it wasn't long enough, the carriage is approximately 16" long!!
Happily collecting things all my life...
