Glasgow's Subway system has been suspended during rush hour after a train broke down.

Operators Strathclyde Partnership for Transport (SPT) advised passengers that the Inner Circle had been brought to a halt shortly after 6.30am on Thursday.

At 7.49am, the Outer Circle was then suspended.

SPT apologised for the disruption and advised passengers that replacement buses had been organised between Govan and Hillhead, and from Partick to Ibrox.

By 9am, the outer circle was back up and running.

Posting on Twitter, SPT said: "Outer Circle is now running with additional trains.

"Inner Circle still suspended but shuttle Subway service running from Partick to Ibrox.

"Again, apologies for the inconvenience. Thank you for your patience."
