Some rail services have been suspended due to a yellow weather warning in place for heavy rain in the Highlands and north east of Scotland.
ScotRail has advised there will be no direct services running between the central belt and Aberdeen and Inverness from Friday morning until Sunday.
Flooding is expected to affect some parts of the country in the coming days after forecasters extended the weather warning until midnight on Monday.
The latest Scottish Flood Forecast said “significant flooding impacts” are likely in the north east on Friday and Saturday due to torrential downpours.
The Met Office yellow weather warning covers Aberdeen, Aberdeenshire, Angus, Dundee, Perth and Kinross, Stirling and Edinburgh – most of which saw prolonged downpours cause problems for residents last week, including flooding.
ScotRail services from Glasgow and Edinburgh to Aberdeen and Inverness have been suspended, though they will run to Dundee from Glasgow, and to Perth from Edinburgh.
A shuttle train service will operate between Inverness and Perth and Aberdeen and Dundee, but it will be subject to delay due to speed restrictions imposed as a precaution.
This is because heavy rain is forecast in areas which already have high water levels and saturated ground after Storm Babet.
Journeys are expected to take longer than usual and customers are advised to check before travelling.
LNER services between Edinburgh and Aberdeen are cancelled and a rail replacement service will run instead.
LNER has also advised that services between Edinburgh and Newcastle will be subject to minor delays due to speed restrictions.
TransPennine Express will be running a limited service between Berwick-upon-Tweed and Edinburgh only, with a heavily reduced service running between Edinburgh and Newcastle. Most trains will be revised to start/terminate at Newcastle and are not calling at stations towards Edinburgh.
CrossCountry southbound services will run on a reduced service.
Meanwhile, repairs at Morpeth are also disrupting services between Scotland and England.
David Simpson, ScotRail service delivery director, said: “The Met Office has issued a yellow weather warning for heavy rain across the Highlands and north east of Scotland until Sunday.
“Our first priority is always to ensure the safety of our staff and customers.
“As a precautionary measure, speed restrictions will be in place across the Highlands and north east, which will result in extended journey times and the removal of some direct services.
“We ask customers to keep an eye on our website, app, or social media feeds for live updates.”
The latest flood forecast issued by the Scottish Environment Protection Agency said significant flooding impacts from rivers and surface water are likely in the north east on Friday and Saturday.
There is also a risk of further impacts in areas recovering from recent flooding.
It said: “River levels are not expected to be as high as experienced during Storm Babet but as the rain will be falling on to already wet ground, flooding from surface water run-off may also cause impacts.
“Caithness and Sutherland, Easter Ross and Great Glen and the south west of Scotland may also experience some localised flooding due to persistent and heavy rain.”
Network Rail Scotland warned: “More extremely heavy rain is on the way. It won’t be to the levels from Storm Babet, but it will affect the same areas already with saturated ground. It will bring a risk of flooding.”
