Hi Mike, I have just joined WT and have stumbled over your veritable goldmine of information on Gresley carriages, which I have been absorbing like blotting paper. It really is a brilliant resource and many thanks for posting all this information up.
One area I am puzzled by, and which you don’t seem to have covered yet, is footboards; their depth and width. Some seem to be full length along the whole solebar whilst others seem to be fitted just under the doors. What was the rule on these (I think I read somewhere that turnbuckle underframes had full length but angle iron a series of short ones to fit under the doors)? I should be very grateful for any help you could offer here.
Many thanks Mike and these drawings are all very helpful. In terms of the length of the solebar mounted footboards I seem to recall reading somewhere (maybe Michael Harris’s book on LNER carriages) that they were full length on turnbuckle fitted solebars (both sides?) but when angle iron was used the LNER shortened them to just be under the doors. I have seen images showing full length footboards on the compartment side on angle iron fitted carriages, so did that continue? I am sorry to keep firing questions at you but I am currently constructing some etched brass kits and want to try to get them as right as I can.
When I was into building Gresley corridor 'wooden walls', available photos indicated that the pre-1930 Turnbuckle trussed underframes had full length running boards both sides and the earlier buffers. Angle-trussed underframes had full length running boards on the all-door compartment side only. Brake end coaches appeared to have a one piece running board at the luggage end and short footboards under the corridor passenger doors. However, by BR days the footboards were in short lengths under the guards door and a separate board under the twin luggage doors on some coaches.
I went off photos in 'Gresley coaches' by M. Harris (David & Charles 1973). Also the later 'LNER Carriages by M. Harris (Thomas & Lochar 1993). Other good sources are the Jane's/ Ian Allan colour albums covering the E. Region.
As I stated earlier it is very dangerous to make generalizations. On turnbuckle underframes there are end door vehicles with stepboards at the ends only and there are certainly 52'6" vehicles with individual stepboards. I suspect what you are referring to are vehicles with compartments featuring external doors to each compartment.
Thank you both for your helpful posts. I am building a Comet dia 130 corridor composite given to me as a present, but the under frame instructions and guidance are notable as much for what they don’t say as what they do. I will proceed on the basis of a full length footboard on the compartment side and four individual ones on the corridor side.
