Trains on the West Highland Line tomorrow have been cancelled because of Storm Caroline.
With the Met Office predicting wind speeds of up to 90 miles per hour, the service via stations including Garelochhead, Arrochar & Tarbet and Helensburgh Upper is among those to be suspended by ScotRail.
The company has said that a safety inspection will be carried out in the morning, and a further decision will be taken about when to resume services.
A flood alert has also been issued for Argyll and Bute by SEPA, stating: “A surge and large waves will bring the risk of spray and wave-overtopping to exposed parts of the coast on Thursday.
“This may cause isolated flooding to low-lying land and roads. The times of greatest risk are around high tide on Thursday morning.
The railway line from Helensburgh Central to Glasgow has been dogged by problems including ‘slippery rails’ at peak times every day this week, but as yet there has been no specific warning for this route tomorrow.
David Lister, safety and sustainability director at the ScotRail Alliance, said: “With the Met Office predicting wind speeds of up to 90 miles per hour, we have taken the decision to suspend some services from the start of service on Thursday.
“This isn’t a decision that we have taken lightly, but the safety and security of our staff and customers must come first.
“Our staff will be working round the clock to get services back to normal and get customers moving as soon as possible.
“Customers should keep up to date with the latest information by checking @ScotRail, the ScotRail app or the website.”
