PASSENGERS have hit out at SPT as services on the Glasgow Subway’s outer circle remain suspended this afternoon.

Staff first raised the alarm during the morning rush-hour at 8am, and said: “Outer circle suspended due to defective train at Kelvinhall. Apologies for any inconvenience. Inner circle is still running.”

Furious commuters slammed the travel provider, with one labelling the situation “utter rubbish.”

As of noon, services on the circle are still not up-and-running.

Glasgow Subway said: “Apologies. All outer circle remains suspended. We are working to get normal service resumed ASAP. Extra services are running on inner circle and a shuttle service is operating between Govan and Patrick.”

The outer circle has since opened.
