Thousands without power four days after Storm Eowyn

On the trains, ScotRail advised customers to expect a continued disruption of services.

Teams of Network Rail engineers have been checking routes through the night since Friday and carrying out repair work with around 500 individual incidents reported.

These include more than 120 trees on tracks, damaged overhead wires, power supply failures and other objects and debris blown onto the line.

David Ross, ScotRail communications director told BBC Radio’s Good Morning Scotland programme it had been “a very challenging weekend” and there was “still significant impact across the country”.

He said: “A lot of work has been carried out over the course of the weekend by colleagues at Network Rail.

“The vast majority routes are up and running but there is still ongoing disruption is some parts of the country.”

He said in Ayrshire and Inverclyde damage to overhead wires are causing cancellations, overhanging trees in the Whifflet are causing disruption and trees are still falling onto the lines in Lanarkshire.

“Some parts of the country where we are only just finding in the last short time discovering further problems,” he added.

“It is a changing picture and it will change over the course of the morning again.”

He warned some damage won’t be a “quick fix” and disruption could last a few days.
