Police have released a CCTV image of a pedestrian who "risked his life" on a level crossing in Nottingham.
The man was photographed on Carlton crossing, on Victoria Road, as the barriers were coming down and the red lights flashing.
British Transport Police said they were treating the incident, on 2 November, as trespassing and have appealed for anyone who can identify the man.
Sgt Rob Bowley said the act could have had fatal consequences.
He added: "Incredibly some people are still putting their lives on the line by ignoring warning sirens and trying to dash through the crossing which, last year, resulted in 13 people losing their lives."
