An official investigation is underway as to find out why a rail freight tanker carrying kerosene and diesel derailed in Ayrshire, causing its contents to create an inferno earlier today.
The train derailed at 6.25am this morning near a bridge outside Stewarton rail station, Ayrshire.
Six of the train's ten wagons overturned and a bridge has collapsed although the locomotive remained upright.
Firefighters from Strathclyde Fire & Rescue extinguished the blaze shortly after midday.
Colin Bayes, Scottish Environmental Protection Agency (SEPA) director of environmental protection and improvement said: "The emergency response to the incident may continue for some time. Once the emergency services have declared the site safe for access, we will be undertaking a detailed inspection."
Network Rail and the Rail Accident Investigation Branch are at the scene to look at possible causes.
