At least 14 people suffered different injuries in a train crash in the English city of Salisbury on Sunday.
British police affirmed that no one was killed in the incident, while 14 people were injured.
The driver of one of two trains involved in a collision has suffered injuries believed to be “life-changing”, the police added.
Passengers described difficult moments when the Great Western and South Western Railway services crashed.
A carriage has initially hit an object, and the second train then crashed into it.
British Transport Police (BTP) said “a number of people” suffered injuries in the incident, which occurred at Fisherton Tunnel close to London Road in the city.
Rail services have been disrupted on Monday as a result of the crash, with cancellations to several journeys.
The disruption on the line is likely to last at least a few days, with a senior rail source suggesting the position of the crash – half in and half out of the tunnel – meant recovering the train carriages would be more complicated and take longer.
Martin Frobisher, Network Rail’s safety and engineering director, said it was too early to say what had caused the collision.
He said: “Passengers must have had a really scary experience and we’re very sorry for that.
“A detailed forensic investigation into what happened is now taking place.”
He said they could not say if the first train hitting an object caused the collision.
Mr Frobisher added: “It’s far too early to speculate and there is a lot of contradictory information.
“It’s the start of the process so we really don’t know the facts at this point.”
