As reported in later editions of last night's Evening Times, train services on main routes from west to east were yesterday cancelled or delayed. On a third day of chaos, commuters were warned of "severe disruption" because of overhead wire problems between Airdrie and Bellgrove.
Network Rail confirmed the disruption was due to an overhead power fault near Blairhill, caused by tree branches coming in to contact with electric power cables.
Services between Edinburgh and Helensburgh Central, Milngavie and Balloch and Dalmuir and Springburn were affected. Some angry commuters, travelling from the east to Glasgow, complained their journey took more than three hours.
The problem first occurred at around 7.50am and was repaired by 10.20am.
Alternative road transport was laid on for passengers who were able to use their tickets to board FirstGlasgow buses or the underground.
A Network Rail spokesman said: "We understand the inconvenience this has caused the public and apologise for the disruption to journeys.
"Our engineers have been working hard to resolve the issue as quickly as possible, and to put in place plans to improve future reliability and performance on the routes affected."

The 53-year-old said: "People were really angry because the same thing happened on Monday night when we left work.
"All the trains were off indefinitely. We had to get the bus from Ingram Street and the bus came and it was full. And then we get to the station this morning and they don't know when the trains are getting back on."
Yesterday, Glasgow passengers faced misery when a train broke down between Charing Cross and Patrick.
It caused delays and cancellations on Strathclyde North services during the busy afternoon rush hour.
On Monday, a signal fault caused further delays. Both incidents affected thousands of commuters.
