TRNSMT attendees were forced to evacuate through the Glasgow Subway tunnel after a train broke down.
The Outer Circle of the city’s transport network broke down between Kelvinbridge and St George’s Cross for around an hour on Saturday afternoon.
Passengers were asked to evacuate the train and led through the dark tunnel to the nearest station.
It is understood hundreds of passengers travelling to TRNSMT were impacted by the disruptions.
Services to the Outer Line have since been restored and the Subway is running as normal.
A spokesperson for SPT said: “The Subway Outer Circle was suspended due to a broken-down train.
“Passengers were detrained, as is normal practice if break down is mid tunnel, to the next station.
“All services have now resumed, and Subway is running as normal.”
