Although I haven't started building the layout yet (next month maybe?) I have been assembling a few trains to run on it, especially some reasonable length ones, and here's a couple of them (straight from the box, no weathering yet or replacement couplings).

(Note that in these photos the trains are more or less plonked on temporary track - the DB is on 00 track on the new DRAG TT2, but has humps over the board joins where the sleepers haven't been removed yet; and the Western and Mk1s are on P4 track on the old and soon-to-be-replaced TT1).

This is the down Ilfracombe portion of the Devon Belle around 1953. The formation is correct, and all the Pullmans ran on the Devon Belle, but maybe not in the same rake.

From the locomotive the cars are: Brake 3rd no. 27, Kitchen 3rd no. 61, Kitchen 1st IBIS, Parlour 1st ROSEMARY, Kitchen 3rd no. 31, Kitchen 1st MINERVA, Kitchen 3rd no. 171, Guard 3rd no. 208, Observation no. 13.

Then, moving on about 10 years we have the Wolverhampton-Penzance 'Cornishman' at about the time when the pure chocolate and cream rakes were getting the odd maroon replacement. From the locomotive the formation is BSK-SK-SK-CK-CK-RU-SO-SK-BSK.
