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. Techs have been on site and repaired the fault and all lines are open once more.

When this usually occurs, trains 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 have been to investigate, and resolved the problem.
