Northern Line Suspension Disrupts Edgware Commuters

Edgware residents travelling into central London this morning face significant disruption after Transport for London suspended northbound Northern Line services between Charing Cross and Camden Town. The suspension, caused by a signal failure at Warren Street, began before 06:50 on 31 July.

The disruption compounds wider issues across the Tube network. The Circle line is fully suspended due to a points fault at High Street Kensington. The District line has no service between Earl’s Court and Edgware Road, with severe delays affecting routes from Ealing Broadway, Richmond and Wimbledon to Tower Hill.

Impact on Barnet and wider London

While the Northern Line suspension directly affects Edgware, other parts of Barnet may experience knock-on delays. The Metropolitan line, which serves Moor Park and Watford, is running with severe delays due to train cancellations. Minor delays are also reported between Harrow-on-the-Hill and Uxbridge.

The Mildmay line, which connects to the London Overground network, is experiencing severe delays due to an operational incident in its depot. This has also caused minor delays on the Lioness line. The Piccadilly line remains suspended between Cockfosters and Uxbridge for planned upgrade works.
