Cancellations appear to be mainly from Oldham depot - so Tranche two. Frustratingly Bee Network only list the routes that may suffer from cancellations - but not the actual journeys! These lists have appeared daily since Saturday but disappear after that day.

Further timetable changes for Tranche One routes (plus non-franchised 150) are appearing on Bee Network pagesTimetable changes coming for the Vantage (do they still use that name anywhere?) routes from April 7th.
There will be two extra V4 journeys in the morning, and timetables throughout the day will change to improve reliability by increasing running times. Off peak journey times towards Manchester seem to be increased by 6 minutes, some shoulder peak journeys have increases up to 15 minutes.
It should improve reliability, but in the longer term if TfGM want to increase passenger numbers they need to be reducing the impact of traffic on journey times.
