Commuters in London are being warned to avoid Waterloo Station after a train derailed in rush hour on Tuesday morning.
The disruption began after a South West Trains (SWT) service collided with a Network Rail engineering wagon.
The incident was confirmed by the rail service on Twitter, who said a “points failure/operating incident” was the cause of the collision.
Pictures on Twitter show the SWT carriages leaning off the rails, against the wagon, as rail service personnel work to restore the service.
London Ambulance Service said it had examined three people after the train derailed, but confirmed they did not need hospital treatment.
Waterloo Station continues to undergo disruption due to a number of platform closures as part of an engineering project.
This work is scheduled to last until the August bank holiday weekend.
