Train services between East Kilbride and Glasgow were affected yesterday due to a trespasser on the line.
ScotRail announced on Twitter that trains going between East Kilbride and Glasgow Central were either delayed or terminated due to a trespasser on the railway between Hairmyres and Busby.
Police officers were reportedly seen walking along the tracks at Hairmyres station.
British Transport Police (BTP) today confirmed a man had been trespassing but had already left the railway line before police arrived.
A BTP source told us: "Officers were called to Hairmyres station at 1.44pm following reports of a man trespassing.
"Officers quickly attended and conducted a full search of the tracks and nearby area however the man was believed to have already left the scene.
"Enquiries into the incident are ongoing."
