NETWORK Rail has been taking steps to plan for extreme weather conditions.

As previously reported, the MetOffice has issued a yellow warning for snow in the north of Scotland.

But temperatures are set to drop further across the country on Wednesday. 

Yesterday, Network Rail held an extreme weather teleconference with infrastructure teams and train operators to discuss proactive measures to take to keep trains moving.

As a result, engineers are applying de-icing fluid to junctions.

Some defective heating strips are being repaired and employees will be patrolling tunnels overnight, removing icicles which could damage trains.

Meanwhile, a locomotive with a mini snowplough attached will leave Inverness first thing on Wednesday, ahead of ScotRail’s 5.36am service to Glasgow Queen Street.

It’ll remain on standby throughout the coming days just in case it’s needed.

Network Rail added: "Staff will be on standby at key junctions, and we're prepared to clear snow if necessary.

"Working with @ScotRail, we’re readying all stations for the cold too, with grit and de-icer being used to keep you safe, though you should still take care while you’re out and about."
