Hopes Raised that Tube Improvements Could End Tennis Chaos
Fleur Anderson says progress made on Wimbledon branch services

Putney MP Fleur Anderson has praised the progress being made to improve the reliability of the District Line’s Wimbledon branch, following a visit to the South Western Railway signalling centre this week.
The visit comes as engineers race to complete upgrades designed to prevent the signal failures that disrupted journeys during last year’s Wimbledon Championships.
Ms Anderson met representatives from South Western Railway, Network Rail and Transport for London, reviewing works that aim to strengthen the resilience of the shared section of track between East Putney and Wimbledon. The improvements include comprehensive drainage upgrades, faster fault-detection systems and new rapid-response repair protocols — all intended to reduce the risk of breakdowns during one of London’s busiest sporting events.
“The signal failures during the Wimbledon Championships were unacceptable,” she said. “We face these issues frequently, but when they occur during such a significant event, it makes national headlines. I insisted on immediate action, and I’ve been following up ever since. Today, I’m encouraged to see the dedicated efforts from TfL, South Western Railway and Network Rail to enhance reliability, ensuring our community can travel seamlessly during this year’s events.”
The Wimbledon branch has long been the weak link in the District Line network. While much of the rest of the line was modernised under the Four Lines Modernisation (4LM) programme several years ago, the Wimbledon section still relies on older track circuits and signalling equipment shared with Network Rail. When those systems fail, delays ripple across the entire District Line, often affecting passengers far beyond south-west London.
Recent months have seen tangible progress. All 77 track circuit boxes along the branch have now been upgraded, improving fault detection and reducing the time needed to identify and fix problems. Drainage improvements have also been completed to prevent flooding — a recurring cause of signal failures in the low-lying sections near Southfields and Wimbledon Park. Engineers have also introduced new protocols to speed up repairs and restore services more quickly after disruptions.
The integration of South Western Railway into public ownership has helped accelerate coordination with Network Rail, which manages the infrastructure south of Putney Bridge. The collaboration has been credited with smoothing communication between operators and enabling joint maintenance schedules.
Transport reliability during the Wimbledon Championships has been a recurring concern. In 2024, severe signal failures led to long delays and overcrowding at Southfields and Wimbledon stations, forcing spectators to queue for more than an hour to reach the grounds. Similar problems occurred in 2023, when a combination of heat-related track faults and staff shortages caused cancellations on both the District Line and South Western Railway services.
TfL has since pledged to strengthen its contingency planning for major events, including deploying additional staff at key stations and improving real-time passenger information. The new signalling link between the Wimbledon Area Signalling Centre and London Underground’s Hammersmith Service Control Centre, due to go live later this year, is expected to further reduce the risk of cascading delays.
The Putney MP also used her visit to call for more trains to stop at Wandsworth Town, arguing that better connectivity is essential for residents and visitors alike. “While I’m pleased with the progress made, residents will remain cautious until they see tangible improvements,” she said. “I will continue to hold our rail operators accountable and ensure they provide regular updates on the advancements being realised.”
With the Championships just weeks away, the upgrades offer cautious optimism that this year’s tournament will be remembered for tennis rather than transport chaos.
