Police investigating a crash on the A69 which ended with a car being struck by a train have released new details about their investigation.
The crash happened at around four o'clock on December 5th, between Greenhead and Haltwhistle when a black Range Rover left the road and crashed onto the railway line where it hit the side of a freight train.
Travelling in the Range Rover was a mother and her two sons - aged eleven and fifteen.
The 11-year-old boy suffered serious injuries and was airlifted to the RVI.
He remains in a critical condition with potentially life threatening injuries.
The mother and 15-year-old boy were treated for minor injuries at the scene.

"Our enquiries have led us to believe that the Range Rover swerved to avoid an as yet unidentified vehicle which was travelling towards it in the wrong lane.
The Range Rover swerved out of its path and came off the road, crossing the eastbound carriageway, going through a fence and hitting the side of a passing freight train.
It does not appear that the Range Rover was struck by the other vehicle before swerving off the road, however we are treating this as a hit and run.
We are now making enquiries to trace this vehicle."
