The LNER Encyclopedia

How many variations are there of Sleeper built PW huts?
I believe that there are at least 3 types in the LNER NE area.
Any detail as to why or any sketchs, Drawings etc would be welcomed.

There's an Ian Holloway drawing of one type in 'North Eastern Express' No. 26 (February 1967), later reproduced in their 'Album of North Eastern Railway Drawings' of 1981.

Hope this is helpful...

Thanks for that.
