Fears of a possible explosion triggered by a warehouse fire in Bonnybridge caused massive disruption for rail travellers this morning.
The main line between Glasgow and Edinburgh was closed after the blaze ignited at a small industrial unit on Greenhill Road at around 5 a.m.
Fire fighters established a 200m exclusion zone around the site due to the possibility of propane gas cylinders being inside the building.
Police warned nearby residents to stay away from their windows.
It is understood that one house closest to the site was temporarily evacuated.
The incident meant that the rail network in central Scotland was paralysed just as thousands of people were preparing to head to work.
All services from Falkirk High and Grahamston stations were suspended, but were due to resume by this afternoon.
The cordon around the site was lifted at 8.30 a.m. after it was confirmed that the canisters in the shed did not contain any explosive material.
Central Scotland Fire and Rescue Service received more than 20 calls reporting the fire at 5.09 a.m.
Two pumping facilities from the Denny, Larbert and Falkirk stations attended the scene, as well as an aerial ladder platform from Falkirk and a water carrying vehicle from Dunblane.
The fire has now been extinguished and officers are now dampening the remains of the building, which was completely destroyed.
Investigations into the cause of the fire are ongoing.
