A person has died and a child is in hospital with life-threatening injuries after their car was struck by a train at a level crossing.
It happened at about 08:50 BST at a crossing on Station Road in Hoghton, near Preston in Lancashire, British Transport Police (BTP) said.
Paramedics and the fire service are in attendance, but there have been no other injuries reported, while the Rail Accident Investigation Branch (RAIB) announced investigators have been sent to the scene.
"Sadly, a child has sustained life-threatening injuries and has been taken to Alder Hey Children's Hospital for further treatment.
"No passengers from the train required treatment from ambulance crews," a spokesman said.
A BTP spokesperson said: "Two people were in the car and sadly one was pronounced dead at the scene, the other is being taken to hospital with life-threatening injuries."
A spokesperson for RAIB said a team of inspectors has been sent to gather evidence as part of a preliminary examination and "a decision on whether or not an investigation will be launched will be taken in the coming days".
Anyone who witnessed what happened has been asked to contact Lancashire Police.
