Victoria line
The section of Victoria line between Seven Sisters and Finsbury Park stations is the longest between adjacent stations in deep level tunnels on the London Underground network. During the planning phase of the Victoria line, thought was given to converting Manor House into a Victoria line station and diverting the Piccadilly line in new tunnels directly from Finsbury Park to Turnpike Lane via Harringay Green Lanes, but the idea was abandoned because of the inconvenience this would cause, as well as the cost.
