A trackside fire broke out near Clapham Junction on Sunday afternoon, 27 September 2026, damaging signalling equipment on the railway line between Clapham Junction and London Victoria stations. This damage has caused substantial disruption to train services into and out of London Victoria.
Disruptions on Southern, Gatwick Express and Thameslink Services
Southern and Gatwick Express trains have faced severe impact, including cancellations, delays of up to 60 minutes, diversions, and service revisions. National Rail reported disruptions will last at least until 4pm on Monday, 28 September. An “extremely reduced” train service has been operating to and from London Victoria with partial resumption expected from midday or 2pm, although
some sources indicate delays until 4pm.
Train cancellations occurred between 10:30am and 1pm Monday, including services scheduled to arrive at London Victoria at 8:59am and 9:02am from Epsom Downs and Eastbourne. Southern services between Sutton, East Croydon, Selhurst, and London Bridge, along with Thameslink routes connecting Sutton to Kentish Town, West Hampstead Thameslink, St Albans City, and Luton, have been disrupted. Gatwick Express services between London Victoria and Gatwick Airport remain suspended, though coach services to Gatwick are running normally. Southern Rail announced that normal service will resume between London Victoria and Eastbourne/Ore from 4:24pm.
Impact on London Underground and Other Transport Services
The London Underground network has
also experienced delays related to the rail disruption. The District Line suffered severe delays between Tower Hill and Upminster caused by an earlier fire alert at Plaistow station. The Victoria Line reported severe delays due to a track fault at Brixton. Portions of the Northern Line were partially suspended between Edgware and Camden Town after a passenger became unwell on a train.
Additional delays affected the Docklands Light Railway (DLR) due to a faulty train at Bank station. Signalling faults continue to cause disruptions between Streatham and Tulse Hill, impacting Southern and Thameslink services. London Buses, C2C, and DLR accept
valid tickets on alternative routes to ease passenger commuting. Tickets valid for Gatwick Express and Southern services are accepted without extra charge across London Underground and Overground services.
Timelines for Repairs and Service Resumption
Emergency engineering repairs have been underway overnight and continue throughout Monday, 28 September. Despite extensive efforts, full service restoration is expected only by late afternoon, with some disruption potentially lasting until the end of the day. Passengers are advised to allow up to 60 minutes of additional travel time for journeys involving London Victoria station.
Several train services departing from London Victoria have been cancelled or revised in the morning and midday
peak periods. Reduced train speeds have been implemented between Streatham and Tulse Hill due to ongoing signalling faults. Service resumptions include Southern Rail’s announcement of returning to normal operations on the Eastbourne and Ore routes from 4:24pm on Monday.
Official Statements and Passenger Guidance
Southern and Gatwick Express confirmed: “On Sunday, 27 September, there was a fire next to the track in the Clapham Junction area. The fire caused damage to the signalling equipment on the route and repairs are ongoing. As a result, trains between Clapham Junction and London Victoria may be cancelled, delayed by up to 60 minutes, diverted or revised.”
National Rail
advised that disruption is expected to last at least until 4pm, with some indications of prolonged disturbance. Passengers are encouraged to seek alternative routes and consider using London Underground, Overground, and participating bus services where valid tickets are accepted. Coach services connecting to Gatwick Airport have resumed normal operations despite rail suspensions.
