COMMUTERS in Glasgow are facing some disruption on Friday morning, after a signalling fault outside the city led to some train services being revised. 

Scotrail advised passengers through Twitter that a signalling fault between Barrhead and Kilmarnock was causing delays to trains from the city this morning.

The company wrote:"@NetworkRailSCOT staff is currently dealing with a signalling fault between Barrhead - Kilmarnock, which has resulted in our services being delayed.

"Staff are on site and investigating the fault, but until it's been fixed we have to run at a reduced speed."

The routes affected Glasgow Central to Kilmarnock, Glasgow Central to Newcastle/Carlisle via Dumfries and Glasgow Central to Girvan/Stranraer via Kilmarnock.

Scotrail warned these services might be delayed.

In a subsequent update, Scotrail said the fault had been fixed and services are returning to normal.

However, some might still be affected.

It tweeted: "@NetworkRailSCOT has fixed the fault and services are returning to normal. Some services may still be cancelled, delayed, or revised."
