Three people, including the driver, have died after a passenger train derailed in Aberdeenshire.
A major incident was declared and about 30 emergency service vehicles were called to the scene near Stonehaven.
It is thought the train hit a landslide after heavy rain and thunderstorms which causedflooding and travel disruptionacross Scotland.
Six people have been taken to hospital, although their injuries are not believed to be serious.
The incident involved the 06:38 ScotRail service from Aberdeen to Glasgow Queen Street.
British Transport Police said the driver’s family had been informed and were being supported by specially-trained liaison officers.
Efforts were continuing to inform the families of the other two people who died.
Ch Supt Eddie Wylie said emergency services were still at the scene dealing with the “major incident”.
“I would like to reassure the public that this was not a busy service and from CCTV inquiries and witness statements we believe all passengers have been accounted for,” he said.
“Once the area has been made safe then a full and thorough search will be conducted, which is likely to take some time.
“I know many people will understandably have questions and we will be working closely alongside the Rail Accident Investigation Branch and the Office of Rail and Road to establish the full circumstances of how the train came to derail.”
Early indications are that the heavy rain could have been the main factor in causing today’s crash in Aberdeenshire.
One rail industry source says the 06:38 service from Aberdeen to Glasgow was initially halted because of flooding on the line.
The driver apparently contacted control to ask permission to switch tracks.
It’s believed the train reversed and switched to clearer tracks and then continued on its route to Glasgow.
Then it is thought the train hit a landslide and derailed.
However, this initial, unconfirmed version of events should now be closely examined by the UK’s Rail Accident Investigation Branch.
Its job is to establish all the facts.
The train’s computer systems should show key indicators like the speed it was travelling at when it left the track.
In recent years incidents like this on the UK’s railways have become incredibly rare. The last major derailment was in 2007 in Cumbria.
First Minister Nicola Sturgeon expressed her “deepest condolences” to the loved ones of those who lost their lives in the “tragic incident”.
