A closeup view of the entrance to Lothian Buses bus 661G (ex-706) (SN04 AFA), showing the clearance with the edge of the kerb on the West Edinburgh Busway. It was photographed while standing in the westbound lane of Saughton West Halt, while being shown off to dignitaries - see this image of the whole bus. Buses were operating at the same time however - see this image of 626G passing in the opposite direction.
