The families of two girls killed by a train on a level crossing in Essex have spoken about their devastation.
It is believed the teenagers were on their way to catch a train
The parents of Charlotte Thompson said they did not know how they would go on without their "beautiful girl".
Olivia Bazlinton's family said the 14-year-old schoolgirl would be "forever engraved in our hearts".
It is believed the pair were crossing the tracks to get to Elsenham station despite red warning lights when they were hit by a through-train.
An inquiry is under way, but it is being treated as an accident.
The girls, both aged 14, were hit by a Central through-train heading from Birmingham New Street to Stansted Airport on Saturday morning.
It is believed they were attempting to catch a Cambridge-bound train which had stopped at the station.
Reg and Hilary Thompson said their daughter Charlotte, known as Charlie, was a "beautiful, vivacious, generous girl".
Charlotte's parents described her as a 'generous girl'
"We do not know how we will carry on. A fog of emptiness has descended upon us.
"Charlie will never leave us and we will never leave her. In her short life she brought happiness to so many.
"She was an angel in life and she is now an angel who will watch over us."
In a joint statement, Olivia's father Chris, stepmother Nicki, mother Tina Hughes and stepfather Peter said: "Olivia was a very normal, mischievous teenager that everybody loved dearly."
They said Olivia was in Year 9 at Newport Grammar School, and was a "very creative" girl who had many friends.
"Olivia loved to talk, she was fun and smiley... Described as a clown princess, she was someone who could never stay angry at anyone.
Chris Bazlinton said daughter Olivia lived life to the full
"She is forever etched in our minds and engraved in our hearts."
Church congregations at Elsenham, in Essex, were asked to say prayers for the families of Olivia Bazlinton and Charlotte Thompson.
Dozens of bouquets of flowers have been left at the scene of the girls' deaths.
One card read: "Will always be thinking of you. You'll always be in my heart, all my love Sofi x."
Richard Priestley, head teacher of Newport Free Grammar School, where both girls were pupils, said he was "deeply shocked" by the news.
"We will be holding a special assembly on Monday for the girls and we will be offering counselling," he said.
"They were full of life and had everything ahead of them. Sadly it has come to an end."
A spokesperson for British Transport Police said they were treating it as a tragic accident.
