- A signalling problem caused widespread train delays across the UK rail network on Tuesday afternoon.
- National Rail confirmed the disruption stemmed from issues with radio communication systems, preventing train drivers from connecting with signallers.
- This led to trains running at reduced speeds and extended journey times for passengers.
- Numerous operators were affected, including the Elizabeth line, London Overground, and Great Western Railway, among others nationwide.
- Although the communication issues were resolved just before 2pm, disruption was still anticipated until at least 3pm.
