The next stops being Elstree South and Bushey Heath, both would have been near the Aldenham Works, London Transport's main bus overhaul depot.

Post-war the project did not restart because the Town and Country Planning Act 1947 had created the Metropolitan Green Belt around London curtailing further urban expansion.

[3] The W&ER had planned an extension of the Edgware, Highgate and London Railway to Watford Junction via Bushey, but it had never raised the capital required and its powers to construct a line had expired in 1911.

The T-junction was to be reconstructed as a roundabout to incorporate a forecourt for access to a curving range of shops and a continuation of Spur Road heading to the north-east to a new housing development.

[11][n 4] The station platforms were to be on the viaduct and on a bridge over Spur Road and were to be long enough for nine-car trains being planned for the new Northern line service.

[13] Following the outbreak of war in Europe, work on the station and the extension was suspended in September 1939 and was formally terminated in December of the same year as wartime funding restrictions would prevent completion.

Analysis showed the capacity needed without the Bushey Heath extension could be accommodated by developing LNER's former Highgate depot, and the final part of the route was abandoned on 26 November 1953.

[18] The completed arches of the station viaduct were partially demolished in the 1960s leaving stumps of brickwork in a field and part of the north abutment of the bridge adjacent to Edgware Way.

[21] Following the abandonment of the extension, the unused land between Edgware and Brockley Hill was developed for housing with the western end of Heronsgate, Campbell Croft, Shelley Close and the southern section of Sterling Avenue filling the space.
