Accident investigators have spent the morning studying the wreckage of a Virgin group train that crashed in North-West England last night.
An 80-year-old woman passenger died and five other passengers were critically injured in the accident which happened in a remote area of Cumbria shortly after 8pm last night.
The Chairman of the Virgin Group, Richard Branson, has been to visit the injured and to inspect the scene of the accident.
He paid tribute to the driver who was himself hurt for doing everything he could to minimise the impact on the train.
Mr Branson said the cause of the crash appeared to have been a problem with a defective line.
180 people were on board when the state-of-the-art Virgin Pendolino tilting train derailed at 150 km/h.
Nine carriages of the Virgin train from London to Glasgow were left on their side with some stuck up in the air after the train slid down an embankment.
12 ambulances and 80 firefighters were rushed to the scene of the crash and Royal Air Force Sea king helicopters ferried the injured to hospital.
However, heavy rain and the remoteness of the crash site hampered rescue efforts.
