North passengers have been warned of serious delays this morning after Scotrail cancelled a number of services travelling to Glasgow Central.
The cancellations come after a fault was detected with overhead electrical wires at the station.
Passengers travelling on long-distance journeys have been warned that trains are currently subject to queuing and a spokesman for Scotrail confirmed they were unable to say how long delays may last.
Services at Glasgow Central are not expected to run until later this afternoon.
