Train services across the UK faced significant disruptions on Friday morning due to a “nationwide fault” affecting the critical radio communication system between train drivers and signallers.
The issue has caused delays and cancellations on at least eight major rail lines, including:
Elizabeth Line
Gatwick Express
Great Northern
Southern
South Western Railway
Thameslink
Southeastern
ScotRail
Key transport hubs such as London Paddington and Victoria have been severely impacted, with National Rail advising passengers to expect cancellations and disruptions throughout the day.
The fault has been identified as an issue with the onboard GSM-R radio system, a critical technology used for emergency communication between train operators and signallers. This system ensures safety and coordination across the network.
National Rail has confirmed that an investigation into the root cause of the problem is ongoing. Passengers have been urged to check for updates before travelling and to anticipate potential delays or alternative arrangements.
With disruptions affecting multiple lines and major stations, passengers are encouraged to follow live updates via National Rail’s website or contact their service providers for the latest information.
