SCOTRAIL announced this week the service between Motherwell and Cumbernauld will be withdrawn until further notice.
The company say the service has come to a halt because of a number of trains suffering weather-related damage.
This includes damage from frozen blocks of packed snow and ice falling from undercarriages and then bouncing back upwards.
The company also say water pipes can be frozen. Severe temperatures and bad weather can also result in frozen brakes, affect fuel lines and block electrical cooling systems.
A ScotRail spokeswoman said: "Difficult decisions have had to be taken following the impact on infrastructure and our trains during the extreme weather.
"We are working hard to reinstate services as soon as possible and apologise to customers for any inconvenience caused."
