Can you tell me more?

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 will share updates as soon as they have them.
