The parents of the 15-year-old girl who died after being struck by a train in Hertfordshire this week have paid tribute to their "princess and angel".
Charleigh Disbrey was killed alongside fellow Hertswood Academy pupil Mert Karaoglan, 18, near Elstree and Borehamwood station on Monday.
In a statement, Charleigh's father Matthew Disbrey, 31, and her mother, Sandie Barnes said: "We will never fill the hole that has been left in our hearts and in our lives. Charleigh had two loving and caring families who will miss her every minute of every day.
"We cannot put into words the devastation and loss we all feel. You will be forever loved and missed, our princess, our angel. Our thoughts are also with Mert's family at this incredibly sad time."
The parents' tribute came in a statement released through British Transport Police (BTP) who are not treating the deaths as suspicious.
Mr Disbrey said: "Charleigh, you were my friend, my daughter and my rock - I don't know what I should do without you. Daddy will always love you, princess."
Ms Barnes said: "My beautiful Charleigh, you weren't just my truly amazing daughter, you were my best friend. I love you so much and you will always be Mummy's angel."
BTP Detective Inspector Andy Rose said: "Our thoughts remain with Charleigh and Mert's families and friends - clearly this remains a desperately difficult time for them. While the incident is being treated as non-suspicious, my officers and I are continuing our investigation and working to put a file together for the local coroner. The inquest into Charleigh and Mert's deaths will be held at Hertfordshire Coroner's Court, in Hatfield, at a future date." BTP Detective Inspector Andy Rose said: "Our thoughts remain with Charleigh and Mert's families and friends - clearly this remains a desperately difficult time for them." Anyone who witnessed the incident, or who has further information about the incident, is urged to contact British Transport Police on 0800 40 50 40 quoting B8/LNA of 18/06/2013.
Mert and Charleigh were struck by a First Capital Connect train travelling from St Albans in Hertfordshire to Sutton in south London shortly before 9pm on Monday. Their headmaster has also paid tribute to the two pupils while friends have left flowers outside the academy in Borehamwood, Hertfordshire, as well as posting messages on social media sites.
An inquest into the teenagers' deaths was opened and adjourned to a date yet to be fixed, a spokeswoman for the Hertfordshire coroner said. The cause of death for both was given as "multiple traumatic injuries", she added.
