The London Overground is part suspended this morning due to a fault with the signalling system at Hampstead Heath.
Numerous lines are blocked as a result, causing cancellations and delays between Gospel Oak and Startford / Barking, Transport for London (TfL) said.
Disruption is expected to last until midday, with no trains due to run between Willesden Junction and Camden Road at all this morning.
You’ll be able to use your ticket on local buses if you were relying on travel from any station between Gospel Oak and Walthamstow Queen’s Road.
None of those will be served. Some services between Camden Road and Stratford will also be delayed.
