The chief executive of Network Rail, Mark Carne, has made an "unreserved apology to those who have been let down" by the authority's failings in managing the risks of level crossings.
Speaking on Daybreak, Mr Carne also apologised for the behaviour of Network Rail in dealing with the bereaved.
In response, Chris Bazlinton - father of Olivia Bazlinton, who died at a level crossing in 2005 - said he was "encouraged" by the comments and would be holding Network Rail to account.
Mr Bazlinton added: "I think the future is bright. I think this report will lead to much safer railways."
