Description

A fault with the signalling system between London Bridge and London Blackfriars means that trains have to run at a reduced speed on the line towards London Blackfriars. As a result, trains running between Elephant & Castle / London Bridge and London Blackfriars may be delayed by up to 15 minutes or diverted between East Croydon and London Blackfriars.

Disruption is expected until the end of the day.

Customer advice:

Delays of around 15 minutes are expected between London Bridge and London Blackfriars, affecting northbound services towards London Blackfriars, Farringdon and London St Pancras International.

Short notice alterations are also possible, meaning some late-running services will have cancelled stops, or will terminate and restart at a different station to normal.

For most journeys, you can travel using your normal route but please check before you travel and allow some extra time for your journey - we'd advise an extra 15 minutes.

Tickets will be accepted for no extra cost the following:

• Southern and Thameslink services via any reasonable route including for travel to / from London Bridge and London Victoria

Can you tell me more about the incident?

This part of the network uses track circuits to detect trains. If a circuit fails, the system may think a train is still there, blocking others from moving forward.

Drivers must stop at red signals and get verbal permission to proceed at a reduced speed, which can cause significant delays, especially in areas with long track sections.

Faults can be caused by electronic issues or track obstructions. Network Rail is investigating, and we’ll share updates as soon as we have them.

Compensation:

You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
