ScotRail have confirmed that the Largs to Glasgow service will not be operating until a full inspection of the line can take place, following the impact of Storm Gerrit, and rail bosses are satisfied that it is safe to re-open. 

This afternoon, the line flooded at the Fairlie tunnelhead, alongside the A78 which was also flooded.
