The engineering work that would have switched on the District Line’s new Wimbledon-branch monitoring was called off at short notice over the weekend, two weeks before the Championships.
Transport for London (TfL) has apologised and says the closure was postponed because of “last-minute technical issues,” with no new date yet set.
It was the one job this year meant to cut the risk of a repeat of last summer, when the Wimbledon branch collapsed during the Championships, reliability fell to 69 per cent, its worst in over a decade, and the Mayor of London apologised. The tennis begins again on Monday 29 June, with one weekend of engineering time left before it does.
TfL told us said its representatives had met the All England Lawn Tennis Club (AELTC), the Wimbledon organisers, as the problems became apparent.
Getting an answer to last year’s meltdown has taken a year. Wimbledon MP Paul Kohler won a private meeting with TfL and Network Rail in February and still came away unsure what had been agreed: he told constituents that TfL had confirmed funding to modernise the signalling, while the meeting notes we obtained put the commitment at a £200,000 to £300,000 monitoring package, and called full modernisation unfeasible “within any reasonable planning horizon.”
Putney.news has asked three times, under freedom of information, for last year’s reliability figures. TfL has refused every time, and our complaint to the regulator is still outstanding.
The Lawn Tennis Association asked too. Its Queen’s Club finals fell on the same weekend, so it asked TfL to move the works and let spectators travel. The governing body of British tennis was told TfL “have not been able to do this.” Days later, the works were called off anyway.
What the year did establish is the ceiling of what TfL was ever going to offer. TfL’s own board paper from June 2024 says the line will “not be re-signalled.” A real fix would mean South Western Railway refitting its whole fleet for a four-mile stretch of track and no gain for its own passengers, and that decision sits with the Department for Transport, which has not taken it.
What was achievable was that monitoring package: fault-detection equipment bolted onto the existing, decades-old kit, the work we first reported in May. Earlier this month, Putney MP Fleur Anderson confirmed the hardware is now in. The weekend’s work was the step that connects the equipment up and turns it on.
Listed on Thursday, pulled on Friday
The works were down to run all weekend and, on the Thursday, were still in TfL’s published schedule, headed “Correct at date of publication Thursday 11 June 2026.” The only warning that they would not go ahead came late on the Friday, in an email to passengers signed up to TfL’s travel updates. Anyone who was not signed up, and anyone who had planned around the shutdown we had told them to expect in our guide on 9 June, had no warning. The Hammersmith and City line’s works for the same weekend were pulled too. By Saturday afternoon, TfL’s live status feed read: “District Line: Minor delays due to the short-notice cancellation of engineering work.”
What passengers got instead was not the managed closure they had been promised, but an unplanned one. On the Saturday morning a signal failure at Parsons Green left the Wimbledon branch with no service from early morning until midday, on the same ageing infrastructure the upgrade is meant to protect. TfL says the failure was unconnected to the postponement. Either way, those who had made other arrangements for a planned shutdown spent the morning living through an unplanned one.
One weekend left
We contacted TfL over the situation. A spokesperson apologised to District line customers for the disruption to their journeys and said the closure had been “postponed due to last-minute technical issues,” with the operator “working hard to restore as much service as possible since.” TfL said a new weekend would have to be planned, that it did not yet have a date, and that the Wimbledon fortnight would not be affected.
Asked why it could postpone the works at the last minute when it had told the LTA it could not reschedule them, TfL drew a distinction between the two: it had wanted to do the work as soon as possible, it said, but once the last-minute problems emerged it was not possible to go ahead.
We have also asked whether the new system will be switched on before the Championships, and how confident TfL is of avoiding a repeat of last year’s debacle. TfL has yet to respond.
One engineering weekend remains before the tennis begins, on 20 and 21 June. TfL’s published schedule still lists no District Line works for it.
The hardware is in the ground. For now, nobody has switched it on. TfL says the Championships will not be affected; whether the new equipment will be working in time, it has not said. The reliability data we have been asking for since the spring is still, it says, coming in the coming months.
What you can do
Readers who want to keep the pressure on can write to either of the two local MPs already on record over the branch, Fleur Anderson (Putney) and Paul Kohler (Wimbledon), or add their weight to the complaint now sitting with the Information Commissioner.
The permanent fix, taking South Western Railway off the branch or forcing a shared signalling standard, needs a government decision that nobody at TfL or Network Rail can make alone, and it has not come. What could be done this year was the monitoring upgrade. Now it looks like that effort is also stalled.
Correction, 15 June 2026: An earlier version of this article said TfL gave no announcement of the postponement. In fact TfL emailed passengers signed up to its travel updates late on Friday 12 June to say the works would not go ahead. The article has been amended.
Great reporting, hopefully keeping up the pressure on TFL.
How amazing that the information commissioner is not responding. It would make more of a story if ANYTHING ever worked as it should do. As for contacting our MPs – hmm .
