At the western boundary, the number of trains not successfully transitioning has been below 0.5 per cent since Trial Operations started in November 2021.

At the eastern boundary, the number of trains not successfully transitioning and experiencing an unsolicited brake application has been 2.9 per cent since the automatic transition was commissioned at the beginning of January 2022. In the last two weeks (to 14 March), this rate has increased to 5.5 per cent.
