The technology uses an electronic system to calculate precisely the position of a train's wheels on the track and a mechanical system to place these wheels in their optimal position when the train rounds a curve. The electronic system monitors the speed at which the wheels are rotating. Due to the wheels' slightly conical shape and the difference in length between the inner and outer tracks on a curved section of track, the system can determine the wheels' exact contact point. Pneumatic struts attached to the wheels then move the wheels to the best position.
Due to a fault with the signalling system earlier today at Rutherglen disruption is expected until 07:00 11/12.
Train services between Larkhall and Milngavie are returning to normal but some services will still be cancelled, delayed or revised.
This morning we had a signalling faults at Rutherglen which is now clear and trains now able to run.
