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."

Network Rail need to approach the safety risks caused by level crossings with "much more urgency", the head of the transport select committee has said.
Louise Ellman told Daybreak some level crossings could be closed, while "others can be changed" if Network Rail prioritised the necessary changes.
A House of Commons Transport Committee report on level crossing safety has been especially critical of Network Rail's handling of Elsenham level crossing tragedy in Essex in December 2005 in which Olivia Bazlinton, 14, and Charlotte Thompson, 13, were killed.
Chief executive Mark Carne followed severe criticism in a report by MPs of Network Rail's treatment of families affected by level crossing tragedies by issuing a "full and unreserved" apology.
"Today, I wish to extend a full and unreserved apology on behalf of Network Rail to all those whose life has been touched by a failing, however large or small, made by this company in managing public safety at level crossings and in failing to deal sensitively with the families affected.
"Nothing we can say or do will lessen the pain felt by the families of those killed or injured at a level crossing. Today NR is a very different company to the one which existed at the time of these tragic accidents." Mr Carne said.
Families bereaved by level crossing accidents will receive a "full and unreserved apology" from the boss of Network Rail today.
The move from NR chief executive Mark Carne followed severe criticism in a report by MPs of NR's treatment of families affected by level crossing tragedies.
Eight of the country's top ten busiest train stations are located within London and they are getting busier each year.Read the full story ›
"These statistics show more and more people are using the train to get to work.
The Government needs to support this with affordable fares and better infrastructure.
That means not just updating our busiest stations, but connecting communities who currently lose out because they are not on the network.
We also need to devolve more investment decisions away from Whitehall to make the railways more responsive to local needs."
"Not just in London but across the country, more people are using the railway, which is helping to generate record levels of revenue to fund better services and improved stations for passengers."
"Our railways are a success story, carrying more people than at any time since the Second World War.
We want to make sure our railways continue to meet the challenge of passenger demand.
That is why more than £38 billion is being spent over the next five years to transform the network.
That means better stations and more trains and services, allowing more people to travel quickly and comfortably."
London's train stations are continuing to dominate the country's rail network - with the eight of the country's top ten busiest stations located within the Capital.
All of the top 10 reported an increase in passengers in the last financial year, according to Office of Rail Regulation figures.
Based on the estimated number of exits and entrances to a station during 2012/13, Waterloo was the busiest station, with numbers, compared with 2011/12, rising 1.9% to almost 96 million.
Second was Victoria in London, with numbers rising 1.6% to 77.34 million, with another big London terminus, Liverpool Street, third with a 2.4% rise to just under 58.45 million.
The largest rise among the top 10 last year was Euston in London where the number of exits and entrances rose 4.9% to almost 38.3 million.
Clapham Junction is the station with the most passengers changing trains, with 21.6m a year using it as an interchange, up five per cent on the previous year.
The expansion of the London Overground network and other route alterations means more passengers are changing trains in the station’s capital.
