Footage of the moment a cyclist narrowly missed being hit by a train has been released by police as part of a rail safety campaign.

The video shows a woman cycling past a lowered barrier at a level crossing in Cambridgeshire, before hitting the brakes and stepping back when she realised a train was approaching.

Richard Schofield from Network Rail, said the woman had put many lives at risk.

"The person using the crossing not only did not hear the train, but ignored the warning lights and barriers, putting her life, the lives of passengers and the train driver in danger," he said.

British Transport Police are appealing for witnesses and want to identify the woman involved in the incident at Waterbeach, at 6.30pm on 12 September.
