Firefighters who responded to the disaster at Stonehaven will be offered mental health support in the aftermath of the tragedy.
Four members of the crews called to the tracks near Carmont were injured while dealing with the accident.
The firefighters were hurt after being struck by an apparently uncontrolled vehicle whilst carrying out their tasks at the site.
Two were treated by paramedics at the scene for cuts and bruises, while a further two were taken to Aberdeen Royal Infirmary after sustaining an impact injury to an ankle and a cut to the shoulder and head.
All four are now recovering at home.
Assistant chief officer Paul Stewart yesterday said: “It was clearly a very difficult and hazardous scene, and it remains so, and we take the safety of our crews very seriously indeed.
“We did have the unfortunate event of four firefighters receiving minor injuries at the scene, two of which attended hospital for a precautionary check-up and two of which remained at the scene.
“So it was a very hazardous and difficult scene but something that the fire and rescue service is well able to manage and deal with.”
Denise Christie, the Fire Brigades Union’s regional secretary for Scotland, said the organisaion will be liaising with the crews involved to help them deal with the emotional trauma of the incident.
She said: “We will be making sure the firefighters get support.
“It may be in the aftermath that they need help. We will be fully supporting them regarding any stress or mental health issues.
“It was a particularly hazardous and difficult scene and our FBU north area officials are assisting and supporting our members through this traumatic time and will continue to do that for as long as it takes.
“Our condolences are with the family, friends and colleagues of all those impacted by this terrible tragedy and our thanks and gratitude goes to firefighters and all emergency services that mobilised and responded to this incident.”
At least 12 fire appliances and specialist resources attended the accident.
The union is also involved with the joint investigation already launched by Network Rail and the British Transport Police.
Ms Christie added: “Our regional health and safety representative met with the SFRS and we will be working closely with the service as and when required.”
