 Nothing substantial was constructed.The W&ER had several proposed routes and stations but was generally intended to branch from the now closed Edgware, Highgate and London Railway (EH&LR) just before Edgware station and take a northerly route, with intermediate stations suggested at various times for Stanmore (London Road), Elstree (for Brockley Hill), Caldecott Hill (for Bushey Heath), Old Bushey, and Heathbourne Road.The line was planned to terminate at a station on the eastern side of Watford High Street, close to the site of Watford Central which was later planned by the Metropolitan Railway.
