Bushey Heath tube station  Bushey Heath was a proposed, but unbuilt, London Underground station in Bushey Heath, Hertfordshire. The planned location of the station was at the junction of the A41 and A411 roads. The station was the last of three planned by London Passenger Transport Board (LPTB) in 1935 for an extension of the Northern line from Edgware. It would have served as the new terminus of the line. There was debate about the name for the station, with "West Elstree", "Caldecote Hill", "South Aldenham", "Aldenham", "Bushey Heath and Aldenham" and "Bushey and Aldenham" being proposed. The previous station on the route would have been Elstree South to the east. The extension was part of the "Northern Heights" project which was intended to electrify a number of steam-operated London and North Eastern Railway (LNER) branch lines and to incorporate them into the Northern line. Much of the land for the extension came from the purchase in 1922 by the LPTB's precursor the Underground Electric Railways Company of London of the unbuilt Watford and Edgware Railway (W&ER). 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 specific route to Bushey Heath was approved by parliament in October 1937. The LPTB's principal purpose for the extension was to stimulate the development of new residential areas to increase passenger numbers. A secondary purpose was to provide a location suitable for a large new depot that was required to accommodate and maintain the new fleet of 1938 Stock trains to be used across the existing Northern line and the lines taken over from the LNER. The depot was to be constructed to the south of the running tracks between Bushey Heath and Elstree South with access from each end. Bushey Heath station was to be located on the east side of the roundabout junction of Watford By-pass (A41) and Elstree Road (A411). The station would have had three tracks with two double-sided platforms. The arrangement placed the station entrance directly next to the roundabout preventing any later extension. The station was to be provided with a large bus station and car park. The LPTB planned to purchase the land on all four sides of the junction and proposed an extensive commercial development around the roundabout including a cinema, roadhouse and around 40 shops.
