The father of a teenager who was killed at a level crossing in Essex has accused Network Rail of a cover-up - as he prepares to speak at a parliamentary inquiry later today.
Chris Bazlinton's daughter Olivia died with her friend Charlotte Thompson in Elsenham eight years ago.
Today he will join the grandfather of a boy who was badly injured at a crossing in Beccles, Suffolk, in front of the Transport Select Committee this afternoon. The inquiry will look at safety at level crossings.
Today Mr Bazlinton said he wanted to know why key documents linked to the investigation into his daughter's death were not made public sooner.
Network Rail says it has promised the families it is committed to making the railways as safe as possible.
