RAIL users are being warned of travel chaos this morning as trains on the Balloch, Helensburgh and Dalmuir lines face delays or cancellations.

ScotRail announced that all lines are currently closed due to a failure of the electricity supply between Glasgow Queen Street Low Level and Bellgrove.

Network Rail Scotland confirmed teams are on-site in Glasgow to examine overhead lines.

Rail bosses said that a small fire caused the electric supply failure.

Whilst overhead lines are switched off as emergency services work to resolve the issue all services on this route - between Edinburgh and Helensburgh, Edinburgh and Milngavie, and Airdrie and Balloch - are subject to delays/cancellations.

Customers are being advised that tickets can be used on Glasgow Citybus routes in the affected areas.
