A four-year-old girl is in a serious condition in hospital after the car she was in collided with a train on a railway crossing.
The youngster was airlifted to hospital in Sheffield and is in intensive care following the incident on Tuesday in north Nottinghamshire.
The driver, a 67-year-old woman, was taken to hospital in nearby Doncaster with neck injuries and bruising.
A British Transport Police (BTP) spokesman said: "BTP officers were called to the rail line at Beech Hill crossing, Springs Road, Misson Springs, Nottinghamshire, following a report of a train striking a car.
"The car contained two occupants, a woman and a child. The child, a four-year-old girl, sustained serious injuries and has been airlifted to hospital in Sheffield, where she is in intensive care. The train, a Lincoln to Doncaster service, was damaged but has remained upright and on the tracks. Passengers were removed from the train and there are no reports of injuries.
"Officers are working to establish the full circumstances surrounding the incident, including how the vehicle came to be on the tracks. This will include establishing whether there were any witnesses to the incident, while specialist officers will also examine the scene and the car in question. The Rail Accident Investigation Branch (RAIB) and Office of Rail Regulation have been notified."
The scene of the collision is an isolated crossing next to a house about two miles east of the nearest village of Blaxton, on flat farmland. It is on a small country lane which connects the B1396 to the village of Misson.
The crossing has barriers which go half way across the road and these were open on Tuesday night, with the red warning lights still flashing.
Speaking at the scene, Inspector Andy Selby, from BTP, said he could not then comment on whether the barriers and lights were working correctly. He also had no information about whether there had ever been other accidents at this site.
Buses replaced trains between Doncaster and Lincoln as a result of the crash.
