Train passengers in the Motherwell area have been warned that services will be disrupted for a fortnight, starting this weekend.
The line between Whifflet and Rutherglen will close for track improvements and bridge work from Saturday, July 11, until Sunday, July 26.
This will affect services between Motherwell and Glasgow Central via Whifflet.
During the closure engineers will remove sections of the track and overhead power lines before digging out the railway embankment and installing a new bridge deck to carry the railway over the new M8 motorway stretch that will connect Bailieston with Newhouse.
Replacement buses will run between Motherwell and Dalmarnock – calling at all stations via Whifflet – and connecting with trains at Dalmarnock.
Motherwell passengers travelling to Glasgow can use alternative services, but trains between Edinburgh and Glasgow Central via Motherwell have been busier than normal at peaks times due to extra passengers using this route while the Edinburgh-Glasgow Queen Street line is itself partially closed for tunnel work.
A ScotRail Alliance spokesman said: “These works are required to ensure that essential upgrades to the motorway network can take place and are timed to ensure minimum disruption to our customers.
“Rail passengers should plan ahead using Journey Planner on ScotRail’s website or the ScotRail app, and be aware that their journeys might take longer.”
The disruption comes as passengers endure fewer trains on Sundays due to driver shortages. Services were cut by a third last Sunday.
There is also a threat of strike action as drivers have rejected a pay offer.
