ScotRail has said blanket 50mph speed restrictions will be in force across all its routes, leading to disruption throughout the day on Monday. It said no services will depart after midday on Monday on the following routes:

Edinburgh – Fife/Perth/Dundee

Perth – Dundee/Aberdeen/Inverness

Dunblane – Perth

Inverness – Aberdeen/Wick/Thurso/Kyle of Lochalsh

West Highland Line (Helensburgh Upper – Oban, Fort William and Mallaig)

Customers with tickets for travel on Monday can use them to travel on services today, on Monday morning or on Tuesday.

ScotRail said: “Storm Floris is expected to break recorded wind speeds for the month of August across many areas, making this an extremely intense storm for the time of year.

“Once the storm has passed, Network Rail engineers will need to inspect the closed lines for any damage, with passengers being advised that services will start later on Tuesday across affected routes.”

A helicopter from Network Rail Scotland will help teams on the ground complete essential checks across the network as quickly as possible, according to ScotRail.
