TRAIN lines across Scotland have been flooded, closed, and endangered amid the early impacts of Storm Jocelyn.

Network Rail gave an update on the state of the country’s rail infrastructure on Tuesday evening, around 30 minutes before services were due to stop for the storm.

The Met Office has issued a series of weather warnings ahead of Storm Jocelyn hitting the UK, with a severe amber warning in place for much of the coastline and islands.

Network Rail announced on Monday that train services would be shut down from 7pm on Tuesday, and they are not due to restart until after Wednesday morning’s rush hour.

Writing on social media, the UK Government-owned company said that train lines were already seeing flooding and damage from Storm Jocelyn.

“We're dealing with several Storm Jocelyn-related issues across Scotland just now,” Network Rail said.

“We've had to close the line between Helensburgh and Dumbarton as a burn next to the railway at Craigendoran has burst its banks, with water flooding onto the railway.

“We've closed the Kilmarnock-Dumfries line due to flooding at Thornhill. Three pumps working to clear the water, but they're being overwhelmed, such is the volume coming down.

“We've diverted a freight train heading for Ayrshire via the West Coast Main Line.”

The company said there were issues with level crossings at Logans Road in Motherwell and at Blackford in Perthshire due to high winds.

It went on: “On the Shotts line, between Cleland and Carfin, we have a shed roof that's blown onto a 15ft high wall above the track. We're trying to remove it safely before it damages our overhead wires.

“At Westerton and Newbridge, we're dealing with damaged tree branches that are now close to our overhead wires. Response and overhead line staff are on their way to both locations, though trains are still running.”

Ahead of Storm Jocelyn’s arrival, the Met Office issued an amber wind warning covering the west coast of Scotland, parts of the north and north east and Orkney between 6pm on Tuesday until 8am on Wednesday.

There are also yellow warnings for rain covering parts of western and southern Scotland and a yellow warning for ice has been issued across northern and eastern parts of Scotland.
