At least nine carriages are believed to have been derailed, some overturned, and six people were still be trapped inside the wreckage three hours after the crash.

The train, the First Great Western express, leaving London's Paddington at 1735 GMT to Plymouth, was in collision with a car ataround 1815 GMT at an automatic barrier crossing at Ufton Nervet, Berkshire, said British Transport Police.

John Divall, the spokesman for the Royal Berkshire Ambulance NHS Trust, said there have been some 150 causalities, including more than 100 walking wounded and "a number of fatalities."

Eye-witness Hayden Allen told Sky News:"I can see the 125 derailed. It's hit a car on the crossing."

"There is not much left of the car. The carriages are off the track and leaning on their sides."

Richard Micklewright, a passenger on the train, said initially he felt a juddering which became more severe as the train derailed.

"The carriage in front remained upright but I could see that the one after that was at right angles to the track," he told the Sky News.

Dozens of emergency vehicles are at the scene, while a spokesman for the Royal Berkshire Fire and Rescue Service said they are treating it as a "major incident."

Emergency services had also set up arc lights and firefighters were using cutting equipment to rescue trapped passengers.
