The leader of South Lanarkshire Council has called on Transport Scotland to come clean over the evidence which led them to ditch the decision to dual East Kilbride's rail line.
Council leader Joe Fagan, who represents the East Kilbride Central North ward, wants the Scottish Government's transport body to turn over the evidence supporting their position to the Council so it can be reviewed.
A sudden announcement in October of a U-turn on track dualling came via Transport Scotland, causing anger among local residents and politicians.
