Thousands of rail passengers in London and the South West of England are facing major disruption after a train partially derailed at London Waterloo.
The derailment, which was prompted by a points failure between Vauxhall and the London Waterloo terminal, has caused cancellations, delays and rerouted journeys across the network.
Engineering staff, police and the fire brigade were seen on the platform at Waterloo with delayed to services into the station expected until at least 1pm.
The derailed South West Trains service was seen leaning the Network Rail engineering wagon after the collision that occurred around 5:40am.
London Ambulance said three people were "checked over" after the derailment but no one required hospital treatment.
Passengers were quickly advised to seek alternative routes and avoid Waterloo while train services are being reduced to avoid congestion at the station.
The derailment occurs as passengers heading into the terminal already face significant disruption amid a significant upgrade to the station.
It came on the same day a commuter train hit the buffers at London's King's Cross Station before fumes forced a brief evacuation during the morning rush hour at Holborn Underground Station.
