UPDATE: The fault has been fixed and services are returning to normal. 

Some Glasgow train services have been disrupted by an air leak. 

The mechanical fault occurred on a ScotRail service from Glasgow Queen Street to Anniesland on Thursday afternoon.

The train has come to a halt as staff on board work to fix the fault.

More staff have been called to the scene to help, but until the fault is fixed services between Glasgow Queen Street and Anniesland via Maryhill are unable to run.

Low level services between Glasgow Queen Street and Anniesland are not affected. 

 

Trains use compressed air for a number of functions such as air brakes, valve actuation, radiator shutters, horns and bells, and air leaks can affect the efficiency of the train.
