Police investigating the crash between a train and a car on the Yorkshire-Nottinghamshire border, which killed a young girl, are appealing for a tractor driver to come forward.
Officers believe the driver was close to the crossing in Misson Springs near Finningley just before the accident on Tuesday afternoon. Detectives say he could hold vital information which may assist the investigation.
4-year-old Emma Lifsey, who was travelling in the car, died from her injuries - and her grandmother was also hurt. Everyone on the train escaped unharmed.
