A 16-year-old who died after he was hit by a train on a level crossing has been described as a "loving son, brother and grandson".
Aidan Blake Russell Mazurke died after an incident at Kildwick level crossing near Keighley, West Yorkshire, on Monday night, British Transport Police (BTP) said.
Officers were called to the crossing at about 10.50pm.
In a statement issued through police, Aidan's family said: "Yesterday our lives changed forever when we lost Aidan.
"He was a loving son, brother and grandson and it is going to take a long time for this to seem real.
