A radio system malfunction has triggered widespread disruption for train passengers across southern England, with significant delays and cancellations expected throughout the day. The technical glitch, which hampered communication between train drivers and signal operators, was resolved by 10:49 AM, roughly two hours after it was first detected.
Operators Affected
The fault impacted multiple train operators, including Southern, South Western Railway, Thameslink, and Gatwick Express. Passengers using these services have been warned to anticipate major delays of up to 90 minutes and potential cancellations, even after the system was restored.
Continued Impact
Despite the fix, National Rail Enquiries has cautioned that residual disruption is likely to persist until the end of the day. Travellers are advised to check their journeys before departing and allow extra time for their trips. The fault caused a cascade of delays that will take hours to fully clear.
In an update, a spokesperson for National Rail said: "Engineers have resolved the radio system issue, but passengers should still expect significant disruption throughout the day. We apologise for the inconvenience caused."
Advice for Passengers
- Check live departure and arrival times before travelling.
- Allow extra time for journeys, as delays of up to 90 minutes are possible.
- Consider alternative routes or modes of transport where feasible.
The radio fault is the latest in a series of technical issues to affect the UK's rail network, raising questions about infrastructure resilience. The affected operators are working to minimise further inconvenience and have urged passengers to stay updated via their websites and social media channels.
