why was the joint line closed? would there of been a case to keep it open?
or what about north of aylesbury why was this closed? it would of been a
decent route to keep as a fast line to london as it was mostly straight.
also a hell of a lot of housing has gone up in the area so it may of been
stupid to close it.
