Network Rail will be carrying out essential maintenance and upgrade work on the West Coast Mainline this weekend to improve journeys for passengers.
Engineers will be working to renew sections of life-expired track at a range of locations between Carstairs and the Border.
Under-track drainage will also be upgraded Lockerbie and work will be carried out to strengthen embankments on the railway.
Only work that is essential to the continued safe running of the network is being carried out and all non-essential activity has been postponed in response to the COVID-19 lockdown.
Services on the West Coast Mainline and some ScotRail services will be affected. Passengers should only travel if their journey is unavoidable. More information can be found on the National Rail Enquiries' website or by checking with individual train operators.
Alan Ross, Network Rail Scotland’s director of engineering and asset management, said: “Our engineers are continuing to complete vital projects to make sure our railway is able to keep critical workers and essential freight services moving.
“We are appealing to the public to listen to the Scottish Government’s advice and only travel if it is unavoidable.”
