LONDON – July 21, 2025 — A major signalling failure at London Waterloo, the UK’s busiest railway station has caused widespread travel chaos, leaving thousands of commuters stranded and triggering a system-wide emergency response.
The incident, which occurred around 05:30 BST, rendered 14 platforms at Waterloo out of service, severely restricting train movements in and out of the central London hub. South Western Railway (SWR), which operates services across southwest England and parts of Greater London, has issued an urgent appeal to passengers: “Do not travel until further notice.”
SWR reported mass cancellations across all its routes, with engineers racing to restore functionality. However, the operator warned that delays and cancellations are expected to persist until at least 16:00 BST, with ripple effects likely to affect evening peak-hour traffic and even spill into the following day.
“Very few trains are able to move in and out of Waterloo,” SWR said in a public statement. “We sincerely apologise for the inconvenience and are doing all we can to resolve the issue as quickly as possible.”
Network Rail confirmed that signalling engineers are working on-site to identify and repair the fault, but warned that any recovery will be limited and slow.
“While we are hoping to restore some services later in the day, these are still likely to be subject to delays and alterations,” a Network Rail spokesperson said. “Customers should please check back regularly for updates. We are very sorry for the disruption to journeys this morning.”
Affected passengers have been informed that SWR will not reimburse taxi fares, but have been granted temporary access to alternative transport services. Valid SWR tickets are being accepted on:
London Buses
Falcon Buses
Stagecoach South and Morebus services
London Underground
Great Western Railway, Southern, and CrossCountry trains
Despite these efforts, many commuters described chaotic scenes at Waterloo and other key stations, with confusion over alternative routes, overcrowding, and a lack of clear communication.
Today’s disruption comes just weeks after SWR became the first rail operator to be taken into public ownership by the Labour government, marking a major shift in UK transport policy. Labour’s second nationalisation move followed on Sunday, when it brought the c2c rail franchise operating between London Fenchurch Street and south Essex under state control.
The incident may now intensify scrutiny on the government’s handling of rail infrastructure, especially as it relates to performance and reliability under public ownership.
Transport Secretary Angela Rayner is expected to make a statement in Parliament later today, addressing concerns about the immediate response, passenger compensation, and long-term infrastructure investment.
Passengers are strongly advised to:
Avoid travel on SWR services if possible
Check live updates via the National Rail Enquiries website or app
Use alternative transport options listed above
Follow official accounts on social media for real-time announcements
Those affected by the disruption should retain their tickets for potential refund or compensation claims, depending on the final duration and impact of delays.
