Train passengers in Falkirk are experiencing delays this morning after a signalling fault.
ScotRail has said the problem is near Edinburgh Park station.
It is delaying Edinburgh to Glasgow via Falkirk and Edinburgh to Dunblane services.
The rail operator has engineers on their way to the site now to investigate the problem.
But the bad news for those intending to travel is that disruption is expected until at least 11.30am.
