Passengers were alerted to an electricity supply failure at Yoker, Glasgow, which caused significant delays to trains running between Helensburgh Central and Edinburgh.
A ScotRail spokesman has just confirmed the disruption has ended.
He said: “Disruption caused by failure of the electricity supply earlier today at Yoker has now ended. Services between Helensburgh Central – Edinburgh, and between Milngavie - Edinburgh via Airdrie and Bathgate are no longer being affected.”
