Thanks for the kind comments. When I first got the films back I felt the photos left the place looking deserted and empty. I'd purposely avoided people if possible (I hung around for ages waiting for them to disperse) and probably tried to avoid the cars on the ramp too. The shots of the exterior were quite difficult due to the shear scale of the building, a more abstract approach might have helped perhaps.
Tin Tin - It's interesting to compare the original furniture (like the wooden railings in Stand 48) with the modern information displays (the backs of which are just visible in the background). Originally all of the signage was consistent across all of the stands but as bus companies competed more against each other, they started to use their own signs and information displays.
Adam - Having thought about it you're right about Scalextric, the ramps take cars above the bus stands, some people have commented they're quite scary to drive up/down.
I recently went back with the intention of documenting how it is now. I took a d*****l camera but once there, I couldn't get into the right mood, although I plan to return with the original equipment/film one day.
