Description

Lines have reopened following an earlier fault with the signalling system between City Thameslink and London Blackfriars. Trains running between London St Pancras International and London Blackfriars may still be delayed by up to 30 minutes, cancelled or revised.

Disruption is expected to continue until 05:30.

Customer advice:

An ongoing fault with the signalling has been disrupting services across the Thameslink network. Some services remain subject to alterations and cancellations, with the following services in particular being affected:

• Services between Three Bridges and Bedford (stopping services via Redhill)

In addition to this, overnight Thameslink services will run to an amended service in order to allow Network Rail to carry out repairs. From approximately 00.30 until 05.00, no services will run in either direction between St Pancras and Blackfriars/East Croydon. The following changes are expected:

• Services will run between Brighton/Three Bridges and East Croydon only, or will be cancelled

• Services will run between St Pancras and Bedford only, or will be cancelled

Other changes to early morning services are likely so please check your journey before you travel and consider travelling earlier or later where possible.

Journeys will likely take at least 60 minutes longer than usual so please allow plenty of extra time for your journey.

Can you tell me more about the incident?

Thameslink understand how frustrating and stressful it is to face repeated delays and last-minute cancellations caused by the recurring signalling fault on this route, especially when you rely on services to get to work and appointments.

This isn’t the level of reliability you should expect, and Thameslink know that the uncertainty these faults create can make even short journeys feel challenging. Please know that your time is valuable, and every delay has a real impact on your daily life — something Thameslink take very seriously.
