that is great thanks, I think it wasn't showing as pink because it isn't fully isolated (it is a source, you can leave, but not get there) and it was isolated by turn restrictions rather than barriers or one ways. I think the facts on the ground are that it is only for buses and taxis, but I will try and visit there at some point over the next few weeks and survey it properly. Off to London protesting against Brexit at the weekend, so maybe I will have a quick peek then!
