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 will share updates as soon as any are available.
