Network Rail said that while it was expecting a “harsh frost” on Saturday morning, it expected timetables to operate as normal.

It warned of up to 15cm of snow on the West Coast Main Line, south of Motherwell and Carstairs, and in higher areas like Shotts and Livingston.

Network Rail also said inland areas of Fife could see up to 10cm, while heavy rain is also likely along the east coast.

It said it was ready to respond to any weather-related incidents but encouraged passengers to check for updates before travelling.
