The father of one of the girls killed on a level crossing on Saturday has called for safety improvements at the station where the incident happened.
Olivia Bazlinton and Charlotte Thompson were hit by a train at Elsenham station where they're believed to have crossed the track to get to the other platform.
Olivia's father Chris now wants the pedestrian gates which react with the signals to be locked at the crossings.
The 14-year-old girls were remembered in their school assembly on Monday.
It's thought the accident happened when the girls used the foot crossing to catch a train from a platform on the other side of the station.
Red warning lights were on but the girls are thought to have been confused by them and were hit by a train travelling in the other direction.
A spokesperson from Network Rail said: "We will look at how the crossing works and look at its history and see if we can reasonably do anything to make a safe crossing even safer."
An inquest into how the incident happened has started.
