Mother's level crossing safety fight
Last month Network Rail was fined £1m for criminal negligence following the deaths of two teenage girls at a level crossing in 2005.
Olivia Bazlington and Charlotte Thompson died at Elsenham station in Essex when they crossed the tracks thinking it was safe, and were hit by a train.
Since Olivia's death, her mother, Tina Hughes, has been working to improve their safety.
