ScotRail have warned of train disruption throughout Monday because fewer trains are able to return on their west coast lines today.
Trains between Glasgow and Largs are affected.
A ScotRail spokesperson said: "Our class 380 fleet of trains which mainly operate in and around Ayrshire and Inverclyde have had to be withdrawn for maintenance inspections to be carried out following the extremely cold weather last week.
"Our engineers are working hard to carry out the inspections but unfortunately, we've not been able to get every train back in service for today which has resulted in cancellations to services operating between Glasgow and Ayrshire and Inverclyde.
"Customers are advised to check the ScotRail app or website or visit www.journeycheck.com/ScotRail for the most up to date service alterations."
