Watford Junction to Euston trains facing 'major disruption'

National Rail has confirmed that a fault with the signalling system at London Euston has blocked some of the lines into the station, cancelling some services and causing up to an hour of delays for those that can still run.

The issue was initially announced just after 12pm, when it was hoped it would be cleared quickly, but by 1pm operators had warned the “major disruption” is likely to last until 4pm.

• Watford Junction to London Euston trains disruption
• Memories of Watford Junction and The Pennant pub in 1980s
• Watford Junction trains cancelled due to strike action

Avanti West Coast, London Northwestern Railway, and London Overground trains are affected.

Update:

⚠️ UPDATE: The fault with the signalling system has been resolved at London Euston.

We're expecting delays and cancellations to services to/from London Euston to continue as our service recovers.
