UPDATE: The line has now reopened.

RESIDENTS are being warned of travel chaos after a tree fell on a train line in Dumbarton and caught fire. 

Network Rail announced earlier today that its teams are responding to the issue at Dumbarton East.

Trains travelling through this area have been temporarily suspended as the power supply has been turned off to allow safe access to the line.

The tree is currently blocking the line and it is understood that the fire affected the overhead wires. 

Images show the extent of the damage.

Rail bosses confirmed that the line remains closed whilst engineers work to remove the tree. 

So far, branches have been removed from the damaged pantograph - special devices mounted on trains to collect current from contact wires - and efforts are ongoing to remove the rest. 

Once the tree is removed it is hoped that power will be restored as quickly as possible allowing services to resume.
