Network Rail is reminding passengers to check before they travel this holiday weekend as engineers will be carrying out work to deliver more reliable infrastructure, improved facilities and better services.
In Scotland, more than £21m is being invested over the bank holidays in improvement projects at sites across the country.
Most services are unaffected by the work, but some routes will see significant changes – particularly on the West Coast Main Line, in Lanarkshire and the North East.
At Abington, on the West Coast Main Line, engineers will be working to install a new track layout and upgrade the signalling systems while between Motherwell and Shieldmuir, engineers will repair and repaint a bridge on the route.
In the North East, the May bank holiday weekend marks the beginning of a 15-week closure to upgrade the line between Aberdeen and Inverurie.
From May 4 until August 19, the railway will undergo a series of closures to allow engineers to double the track between Dyce and Inverurie, carry-out bridge upgrades and deliver signalling enhancements.
Liam Sumpter, Chief Operating Officer for Network Rail Scotland, said: “Over the May bank holidays, thousands of railway staff will be working to deliver a more reliable and better railway for our customers.
“While most of Scotland’s railway will be open as usual, some routes will be significantly affected and we’re advising passengers to check before they travel.
“The work we are delivering this weekend is part of a £4bn, five-year programme of investment that will help to transform rail travel across Scotland.”
