An 18-year-old girl from Croydon died last night after allegedly jumping in front of a train at Wimbledon station.
British Transport Police (BTP), London Ambulance Service (LAS) and London Fire Brigade were called to the scene just before 10.15pm to reports of a person hit by a train.
A BTP spokesman said: "An 18-year-old woman from Croydon was pronounced dead at the scene. Her death is not being treated as suspicious.
"Her family has been informed and a file will be prepared for the coroner."
LAS sent a responder by car, an ambulance crew, the duty officer and a hazardous area response team to the scene after reports of a person under a train.
