Network Rail engineers will be working to complete more than £10m of maintenance and enhancement work over the Christmas and New Year holidays.
Hundreds of railway staff will be out across Scotland to deliver vital maintenance projects, renew life-expired tracks and enhance stations.
Some of the biggest projects will take place in Edinburgh where engineers will be working on new platforms and signalling systems at Edinburgh Waverley station as well as renewing track in Princes Street Gardens over Christmas Day, Boxing Day and New Year’s Day.
In Glasgow, new track will be laid on the busy approach to Glasgow Central, near Salkeld Street south of the Clyde, over the same period.
In North Lanarkshire, a key junction will be renewed at Greenhill, on the lines towards Perth and Falkirk.
The works are being completed on the public holidays to limit disruption for passengers.
Over the festive period, Network Rail will be investing £148m to improve and upgrade the rail network with more than 25,000 members of staff working at over 300 sites across Britain.
Lindsay Saddler, infrastructure director, said: “The projects we are delivering this festive season are vital to the long-term future of Scotland’s railway.
“They will improve the reliability of the service we provide by renewing ageing infrastructure and will help to reduce long-term maintenance costs.
“By undertaking these major engineering works at a time of year when lines are traditionally closed, we’ll also be able to limit the impact of the projects on our customers.”
