Passengers can expect delays to train services all day because of damage to overhead wires.

National Rail says the wires have been damaged between Watford Junction and Willesden Junction - and as a result is causing disruption to services.

The delays are set to last until the end of the day, National Rail said.

The rail company says that trains between Watford Junction and London Euston may be delayed by up to 30 minutes, cancelled or revised.

Avanti West Coast are also running trains at a reduced service on routes between Manchester Piccadilly, Birmingham New Street and London Euston.

Meanwhile Southern trains may be cancelled, delayed by up to 20 minutes or terminated at and started back from Shepherds Bush.

All stations between Wembley Central and Milton Keynes Central will not be served by Southern, according to National Rail.

The rail company said: "Please be aware that trains and stations may be busier than usual during times of disruption, please consider delaying your journey if you are unable to maintain a two metre distance between yourself and other customers."
