In 1961, it was decided that the line would terminate at Walthamstow (Hoe Street) station rather than Wood Street – this would cut costs by £1.4 million, and "satisfactory interchange" with British Railways was available at Hoe Street station. Walthamstow (Hoe Street) was later renamed Walthamstow Central on 6 May 1968 in anticipation of the line's opening). The line was planned to have cross-platform interchanges at Oxford Circus, Euston and Finsbury Park (with the Bakerloo, Northern (Bank) and Piccadilly lines respectively) and at Walthamstow Central to provide a quick and easy connection between the new line and existing services.
