lovely map. I read somewhere that a possible proposal was to make Manor House tube part of the victoria line and Harringay Green Lane station connected to the Piccadilly line. That would be very nice indeed..
Ruth, the plan was to join up Manor House with the Victoria Line, but re-route the Piccadilly through new tunnels Turnpike Lane -Finsbury Park (more direct) meaning no chance of a station in Harringay.. but the whole thing was very expensive and with little if no gain ..so was dropped.
