Description

A fault with the signalling system between St Neots and Peterborough is causing delays to journeys between these stations. Trains running between Stevenage and Peterborough may be delayed by up to 5 minutes.

Disruption is expected until 11:00.

Customer advice:

You can continue to travel using your normal route. Your journey may be delayed through the Huntingdon area by roughly 5 minutes.

Planning your journey:

Please check journey planners and station information boards before you travel and allow extra time to reach your destination.

You can see the live departure boards, and view a live map of the network.

You can use the Thameslink app to find up-to-date information.

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.

Check before you travel:

You can check your journey using the National Rail Enquiries real-time Journey Planner.

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.
