TRAINS to and from Helensburgh Central are subject to disruption during Thursday morning's rush hour because of a signalling fault.

The problem, between Bellgrove and High Street stations in Glasgow, is affecting trains on the Helensburgh-Edinburgh, Balloch-Airdrie, Dumbarton-Springburn and Milngavie-Edinburgh lines.

ScotRail has advised that trains on all the above routes may be delayed or revised until 9.30am.
