Many thanks for the post LNER4479! I've been waiting many - too many - years for this opportunity and bought my latest property with the absolute requirement for such a space.
Although the bulk for my stock is 1930s LNER - including every Gresley Pacific, P2 and the W1 - I do also have a few post-war Thompson and Peppercorn locomotives as well as of course Tornado and Prince of Wales... and a few foreigners which will be allowed out occasionally.
We'd be most grateful of any period photos and information that people have as we progress the project over the next few years.
