FURTHER details have emerged of a fire at Gretna services which tore through a bus and a lorry.

The blaze, which happened on Tuesday, is thought to have started in a bus and spread to a truck parked next to it.

Witnesses have shared photos of the incident on Facebook.

Paul Thomson, who was at the service station, recalled what happened.

"All of a sudden there was a really loud bang from behind us," he said. "On speaking to the lorry drivers that were closer and listening to them telling the fire service what happened, apparently the buses were in convoy and making their way south.

"They said this bus was smoking when the driver parked up, in between two trucks. When he got out to inspect it, he realised it was on fire and couldn’t do anything about it.

"The truck to the left of the bus managed to pull away, but the driver of the smaller truck on the right wasn’t around - and so his truck caught fire and burnt to the ground too.

"The fuel tank ruptured on the bus and started to spill burning fuel down the road towards about eight artics. There was also a 22 tonne propane truck behind us - it certainly could have been a lot worse."

Mr Thomson, who was on his way home to Edinburgh from the Midlands, said it was about an hour before they could leave the services.

Crews from Longtown, Gretna and Annan were alerted at about 6.15pm and were on scene for about two hours.

Longtown Fire Station said: "The crews saved another adjacent lorry, protecting it long enough that it could be safely moved, but the bus and and lorry that were alight were totally lost.

"Thankfully no persons, either the public or emergency services were hurt and a good job was done by all the crews involved."

Police Scotland confirmed that the incident was not being treated as suspicious.

The Scottish Fire and Rescue Service had no details of the cause of the fire when contacted by the News & Star.
