Police try to identify 20 bodies
Police are hoping to use artist's impressions to identify some of the unclaimed bodies found on Britain's rail network in the last 35 years.
Artist Sharon McDonagh has drawn pictures of 20 of the deceased.
None of them is believed to have been the victim of foul play and most were hit by trains.
Police are hoping that the public will help with identification.
It's the first stage of a huge cold case review which could eventually put names to 1,000 unidentified bodies.
