GLASGOW rail passengers have been warned they face lengthy delays due to a signalling fault.

Trains heading out of Glasgow Queen Street have been disrupted after a faulty cable was discovered at Croy station.

Those travelling from the city to the likes of Stirling, Alloa, Dunblane, Perth, Dundee, Aberdeen and Inverness are to be hit with delays of up to 45 minutes.

Commuters have been warned it will take some time for services to return to normal, despite engineers fixing the faulty cable.

Some bus services are accepting tickets and travellers have been urged to check with ScotRail or Network Rail's websites before setting off.

Network Rail said: "The fault with the signalling system between Croy and Larbert has been fixed, allowing the service between Glasgow Queen Street and Stirling/Edinburgh to start returning to normal.

"Trains may still be delayed by 45 minutes, cancelled or diverted via an alternative route, not calling at some stations between Glasgow and Stirling/Edinburgh.

"This is affecting journeys via both Croy and Cumbernauld.

"We anticipate that a normal service will resume by 1pm."
