Key Points
- A Southern train derailed outside Selhurst depot in south London on 4 February 2026, with no passengers on board and no injuries reported.
- The derailment blocked lines towards Norwood Junction and London Bridge, exacerbating disruption caused by a separate signalling fault between Norwood Junction and London Bridge.
- Govia Thameslink Railway (GTR), operating Southern, Thameslink, and Gatwick Express, issued a rare “do not travel” alert during morning rush hour on 4 February.
- The train was re-railed and tracks repaired by evening, but signalling equipment damage and 134 trains left out of position overnight led to continued rush-hour disruptions on 5 February.
- Commuters faced severe delays, overcrowded platforms, and journeys taking up to 90 minutes instead of 20, with services from London Victoria to West Croydon suspended.
- Network Rail teams responded on site, with specialist staff investigating; a comprehensive probe into the cause is underway.
- GTR expects services to normalise later on 5 February morning, apologising for inconvenience.
- Affected passengers can use tickets on alternative routes; London Overground services also delayed.
- The Salaried Staffs Association (SSA) called for a full explanation of the disruptions.
South London (South London News) February 5, 2026 – Train services through south London remain disrupted during this morning’s rush hour following yesterday’s derailment of a Southern train outside Selhurst depot. The empty train derailed without passengers or injuries, but combined with a signalling failure between Norwood Junction and London Bridge, it caused widespread chaos across Southern, Thameslink, and Gatwick Express networks. Operators hope to restore normality later today amid ongoing investigations.
What Caused the Selhurst Derailment?
The incident occurred inside or outside Selhurst depot, a key facility for overnight storage, cleaning, and maintenance of Southern trains. As reported by Railnews.co.uk, the Southern train derailed yesterday, blocking lines and worsening a concurrent track circuit failure. Network Rail Kent and Sussex stated on X:
“We’re responding to a suspected derailment involving a train at Selhurst Depot, which is blocking the lines towards Norwood Junction and London Bridge. This is causing disruption to services in the area.”
No cause has been revealed yet, but Steve Lammin, engineering director at GTR, announced a comprehensive investigation, as cited by BBC News:
“The train is now back on the rails, but we need to remove it from the tracks and assess the infrastructure to ensure it is safe for operation overnight.”
Photographs showed the train upright, with no injuries, confirming Southern’s report.
Network Rail’s Kent and Sussex division added:
“Our teams are on site and specialist staff are supporting the response while the incident is investigated. We’ll provide further updates as soon as possible.”
The low-speed nature suggests a depot manoeuvre gone awry, though details await confirmation.
How Did the Signalling Fault Worsen the Disruption?
A separate failure affected track circuits between Norwood Junction and London Bridge, reducing available lines and forcing slower speeds. GTR spokesperson, quoted by Express.co.uk, explained:
“A fault with the signalling system between Norwood Junction and London Bridge, along with a train derailment at Selhurst depot are causing the disruption.”
National Rail Enquiries noted fewer lines accessible, contributing to the “do not travel” order active for nearly two hours. Tim Hanlon of the Mirror reported Network Rail’s comment:
“We are currently responding to a derailment of a train at Selhurst Depot, which is blocking the lines toward Norwood Junction and London Bridge… Currently, there are no reported injuries.”
This dual hit stranded trains, with the derailed unit obstructing depot exits.
What Disruption Did Commuters Face?
Rush hour on 4 February saw severe chaos, with Thameslink warning of a 90-minute journey from London Bridge to East Croydon versus the usual 20. Commuter Liz Wells told BBC News:
“Trains were arriving but they had to reverse to continue forward. The platforms felt dangerously overcrowded, and the trains were packed; one train that arrived had only three carriages.”
Services from London Victoria to West Croydon suspended until further notice; Gatwick Airport travellers advised to add an hour. Sky News reported cancellations and delays across south-east England persisting into the next day.
GTR confirmed 134 trains out of position overnight, forcing drivers to start from alternate spots on 5 February. London Overground knock-on delays affected broader networks. A GTR spokesperson apologised:
“We are very sorry for the disruption that passengers experienced… We recommend that customers check our website and social media for the latest travel updates.”
When Will Services Return to Normal?
Railnews.co.uk reported the train re-railed, tracks repaired, though signalling damage lingers and trains misplaced. It is hoped services normalise later this morning, per initial updates.
Steve Lammin of GTR, as per BBC News, said:
“Our aim is to restore services wherever feasible and prepare for tomorrow morning,”
spoken on 4 February evening. National Rail anticipated major disruption until 13:00 on 5 February initially.
GTR issued apologies, working with Network Rail for swift resolution. Past similar incidents, like August 2024, saw lines reopen after hours, but this combo prolonged issues.
Who Responded to the Incident?
Network Rail led on-site response, with GTR handling operations. Southern confirmed:
“There were no injuries regarding the Selhurst Depot derailment. However, the derailment means that trains are unable to leave the depot, leading to cancellations and altered services.”
Thameslink’s TLRailUK on X noted:
“A number of incidents are impacting our services. Firstly… Additionally a train derailment has occurred at Selhurst depot.” The Salaried Staffs Association (SSA) demanded explanation, noting “do not travel” rarity outside extreme weather.
What Alternatives Are Available for Passengers?
Affected tickets valid on specified alternatives; check National Rail or operator sites. TfL routes suggested for planning. GTR urged verifying plans before travel.
Express.co.uk live blog advised staying tuned for updates amid live chaos. Mirror’s coverage highlighted platform overcrowding risks.
Is This a Recurring Issue at Selhurst?
Selhurst depot has seen prior derailments, like October 2024 low-speed event disrupting Southern metro until 07:45. December 2025 person-hit incident closed lines near Streatham Common-Selhurst. November 2024 disruptions between West Croydon-Selhurst.
August 2024 affected Gatwick Express, Southern, Thameslink until late evening. Evri Magaci aggregated BBC and Express reports on this as chain reaction sparking union calls.
The depot’s role in maintenance heightens such risks, per historical patterns.
