Footage has emerged of the dangerous conditions on a section of track near to where the train derailed in Stonehaven.
Three people died in the horror crash which was first reported at around 9.45am on Wednesday morning.
Network Rail Scotland had tweeted a video clip of water pouring onto the track near the crash site just nine minutes after emergency crews were alerted to the incident in the Aberdeenshire town.
The tweet said that the water had come from a landslip at Carmont - which is just a short distance away from where the crash is believed to have taken place.
The footage then shows some bushes sprawled over the track as water continues to gush past.
The tweet from Network Rail read: “At Carmont, we’ve had reports of a landslip, which means services can’t operate between Dundee and Aberdeen.”
News of the landslips comes after large parts of eastern Scotland were hit by torrential downpours during Tuesday evening.
Some areas of the country saw around 80mm of rainfall in just a matter of hours as thunderstorms wreaked havoc in Scotland.
The heavy rain appears likely to have played a part in the tragedy in Stonehaven with dozens of emergency crews racing to the major incident at 9.40am today with a landslip suspected to have caused the derailment.
Authorities were alerted after thick plumes of smoke were seen after the passenger train came off the tracks.
The driver of the train and two others on board died while six others were injured with investigations into the incident continuing.
Nicola Sturgeon released a statement shortly after news of the incident emerged.
The First Minister said: “This is an extremely serious incident.
“I’ve had an initial report from network Rail and the emergence services and I am being kept updated. All my thoughts are with those involved."
