A speed restriction has been placed on trains through Barrhead towards Kilmarnock and Carlisle prompting delays.
It is not clear how long the restriction will last, but it has been imposed due to severe weather in recent days and into today.
According to Scotrail, services will be delayed by up to 20 minutes as a result of the measure.
