Passengers have been told to expect continued train delays despite repairs to overhead wires.
There has been disruption to train services today which National Rail said earlier is set to last until the end of the day.
The train service has now announced that the damage to the overhead wires between Watford Junction and Willesden Junction which caused the delays has now been fixed.
But whilst services recover, passengers have been told that trains between Watford Junction and London Euston and Clapham Junction may still be cancelled, delayed by up to 30 minutes or revised.
Meanwhile, southern trains towards Milton Keynes Central won't be able to stop at Wembley Central Station until further notice.
