Southern England train disruption: Full list of affected routes and travel advice

Train services across southern England are disrupted by a significant fault with the train radio system that is preventing essential communication between drivers and signallers. 

As a result, commuters face cancellations and severe delays. While most services are delayed by 45 minutes, South Western Railway has warned of delays reaching 90 minutes.

National Rail Enquiries expects major disruption to continue until the end of the day. Problems began shortly after 9:00 a.m. today, hitting the tail end of the morning rush hour and affecting the entire SWR network. 

The affected operators are CrossCountry, Gatwick Express, Great Western Railway, London Overground, Southern, South Western Railway and Thameslink.

Given the gravity of the situation, SWR warned that services across its entire network “may be cancelled, delayed by up to 90 minutes or revised.”

It went on: “Our operations and engineering teams are working with signallers to find and fix the fault.

“We do not have an ETA (estimated time of arrival) yet for when signalling will be back to normal.” Commuters face cancellations and delays of up to 45 minutes. 

National Rail warns that major disruption will likely last until the end of the day. Passengers are advised to seek alternative routes, while the fault is investigated.
