Police asked the public to help them name 20 unidentified people found dead on Britain’s rail network over the past 35 years, including one who died in Cornwall.

Officers launched a review of cases where people have died in non-suspicious circumstances, including suicide, but have never been traced.

They released 20 sketches of the victims, 18 men and two women, created by Leeds-based police facial imaging specialist Sharon McDonagh.

Most of the deaths were in the London area, but others were in Coventry, Sussex, Cornwall and Hertfordshire.

The cases date back to January 1975 when a woman was struck by a train at Victoria Tube station.

The review, by British Transport Police (BTP) and the National Policing Improvement Agency (NPIA) is the first of its kind but similar cold case reviews will soon take place involving other forces in a bid to clear up unidentified deaths.
