Can you tell me more about the incident?

This part of the network uses axle counters to detect trains by tracking their wheels. If one fails, the system may think a train is still there, preventing 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 debris. Network Rail is investigating, and we’ll share updates as soon as we have them. Thank you for your patience and we're sorry for any disruption caused to your day.

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.
