Watford and Edgware Railway

The Watford and Edgware Railway (W&ER) was a company established in the 1860s in the United Kingdom to build a railway between Edgware in North London and Watford, Hertfordshire, via Bushey. Its planned 6.25-mile (10.06 km) route would have extended railway line which form part of the present-day Northern line on the London Underground network. 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. One of the alternative proposals had it extend the Watford and Rickmansworth Railway from Rickmansworth in the direction of High Wycombe.

The company's continuing failure to raise the capital needed to construct its line may have been partly due to the competition that it would have offered to existing services. Opposition came from the London and North Western Railway to a junction at Watford and from the Midland Railway to a junction at Mill Hill Broadway. Eventually the Great Northern Railway (purchasers of the EH&LR before its opening) bought out the W&ER and continued to develop proposals although nothing was built.
