There's already a Gordon in that range and his shell is longer than that second one, so I thought it looked too squashed to be an A3 or other LNER class (despite the double chimney and what looks to be a banjo dome).
Could the Single be a GWR 3031 (Dean/Achilles)? The protruding firebox and lack of sandboxes (?) near the splashers seem to indicate that. How did I get it wrong when it seemed the easiest and most obvious of all?
For the fourth one: good thing I didn't guess a Haydock Foundry well tank (Sonny) due to the smokebox shape alone. The tank, cab and bunker shapes remind me of an A1 Terrier, but the smokebox more closely resembles a D1's (a class I never knew existed until now).
