Passengers are being warned of cancellations and delays this morning after a train fault caused disruption on services between Watford Junction and London Euston.

Some trains have been cancelled while other services are being delayed by up to 20 minutes.

This is because of a fault on a train between the two stations that is causing services to run at reduced speeds.

On its website, National Rail says: "A fault on a train between Watford Junction and London Euston means trains have to run at reduced speed on some lines. As a result of this, trains may be cancelled or delayed by up to 20 minutes."

UPDATE: Delays have now cleared, with services running as usual.

London Northwestern Railway and Avanti West Coast services are affected by the fault.
