Network Rail chief executive apologises ' for the mistakes made by us in this tragic case'

"On behalf of Network Rail I apologise for the mistakes made by us in this tragic case that contributed to the deaths of Olivia and Charlotte.

"Nothing we can say or do will lessen the pain felt by Olivia and Charlotte's families but I have promised the families that we will make level crossings safer, and we will deliver on that promise.

"Fundamental changes to the way we manage and look after the country's 6,500 level crossings have, and are being made. In recent years we have reassessed all of our crossings and closed over 500. There is still much to do and we are committed to doing what is necessary to improve our level crossings."
