A SIGNAL failure has caused travel chaos in Glasgow tonight. 

The points at Bellgrove junction failed around three hours ago with trains unable to run to Airdrie.

Services between Balloch to Airdrie have been cancelled, delayed or revised and services between Springburn and Milngavie will be cancelled or changed.

Network Rail engineers have been on the scene and have secured a temporary repair which means trains will now be able to serve Airdrie, but not Springburn. 

Scotrail have attempted to secure replacement buses and are telling passengers to consider postponing journeys or making other arrangements.
