Berwick was always one that intrigued me. Obviously, the dual tenancy thing was one thing. However, the construction/style of the Marygate site was also a bit of a hybrid. There were some aspects that were very much Tilling style - the type of "shelter" bolted to the wall, and the style of eaves at the rear of the depot. However, the front aspect of the depot wasn't very Tilling and the type of bricks used weren't standard either, being more like type used on New Street depot.
I didn't know if Galashiels was operated owned or council. I remember Dalkeith all too clearly and believe that Livi was similar as a combined depot and bus station? There was also Kelso, which I thought was a sweet little place to wait for your Seddon.
Confess my ignorance of further North or West in Scotland. The various bus stations (or should I say stances) that predated Buchanan were company owned? Was Ayr owned by Western, and is now the council? Think there was also Largs and Airdrie
How could I have left out Kelso.
Galashiels bus station was owned by First until 2013, when the local council bought it ahead of work starting on the Borders Railway. The replacement Interchange is owned by the council.
