Rail passengers have been faced with disruption to services this weekend after a train derailment.
The train, which was not in service at the time, derailed at Coatbridge Sunnyside on Friday evening.
It was reported to have been travelling at low speed at the time, whilst there were no injuries.
As a result of the incident, services between Helensburgh Central and Edinburgh Waverley, and between Balloch and Airdrie in both directions have been subject to alterations and cancellations.
An emergency timetable has also been put in place with hourly services in operation between Helensburgh Central and Shettleston, Balloch and Springburn, Milngavie and Anniesland, and between Bathgate and Edinburgh Waverley
Engineers are currently on site working to rerail the train and assess any damage to train and track.
The timeframe for services to fully return to normal will not be known until this work is complete, Network Rail said.
The cause of the incident is still under investigation.
A Network Rail spokesperson said: “Our engineers are on-site working to repair and reopen the railway as quickly as possible for passengers.
“The derailment has caused significant damage to the track and work will need to be carried out to repair and replace rails, sleepers and signalling equipment before we can re-open the line.
“We apologise to customers for the inconvenience caused by this incident.”
David Simpson, ScotRail service delivery director, said: “We’re sorry to customers who are experiencing disruption to their journey as a result of this incident.
“Engineers are on site and working round the clock to get the train back on the tracks and return services to normal as quickly as possible, however, we’re expecting some disruption into the working week.
“Customers should check their journey on our website, mobile app, and through our social media channels for the latest information.”
