Passengers may be trapped on train

Fire services attending a train crash outside London say there are reports passengers may still be trapped on the derailed train.

Eight fire engines were originally sent to the scene of the incident after reports that there were a number of casualties.

London Fire Brigade said it had sent three appliances including a fire rescue unit, which includes cutting gear, to assist the operation.

Witness Nicholas Anastasiou said he heard a ‘‘big bang and that was it.’’

He said: ‘‘One carriage is very badly damaged indeed. In the car park there are bits of the train everywhere.

‘‘People are quite badly hurt. There are loads of hurt people here.

‘‘There are people running around trying to help people but I don’t think they can do much because it’s quite bad. All I can see is the last carriage.’’
