Hiya Stranton, this is a bit of a long shot, but I don't suppose you have higher-res copies of those photos of these old victorian loco sheds you'd be willing to share?
I'm currently studying the building as a retrofit case study and yours are the only images I've found of the interiors, it'd be suuuuper helpful if you could and I'd appreciate it endlessly. If I could I'd go and get some myself, but alas, access issues...
