BOTH Subway circles in Glasgow have been suspended after a train broke down.
The company warned travellers on X that the issue happened in the yard and is blocking the entrance to the system.
Engineers are working to fix the problem.
The post reads: "Apologies all, both Circles currently suspended due to a broken-down train in the yard which is blocking the entrance to the system. We are working to get it moving. Update to follow. Apologies for the inconvenience."
