Watford Junction trains will be cancelled or heavily delayed until the end of the day after wire damage.

In the early hours of this morning (April 24) National Rail confirmed that overhead wires between Milton Keynes and Watford Junction had become damaged.

A raft of trains were then cancelled and a reduced service is now operating on National Rail services between Watford and London. This is expected to last until the end of the day.

A National Rail spokesperson said: “Engineering work is taking place to repair damage to the overhead power lines north of Shepherds Bush.

“While this is ongoing, Southern's East Croydon / Watford Junction services will only run between East Croydon and Shepherds Bush.”

Southern trains will not call at Wembley Central, Harrow & Wealdstone, Watford Junction.

Ticket acceptance is in place on Thameslink services, the London Overground, London Buses, alternative Southern Rail services, and the London Underground.

Some trains travelling north from Watford Junction have also been cancelled.

The Abbey Line and the London Overground are running as normal.
