Think the favourites to be left off are the 19, 35, 40, 42, 71, 168, 335 & 520 & 558.

You'll never see the PR1/PR2 missing unless the bus breaks down, then it's replaced within the next trip, whereas the 42 or 168 could be without a bus for the rest of the day.

Operationally, not a good way to do things, although because every route is a contract, something has to go if the resource just simply isn't there. Obviously the Live Tracking on bus times does help, although sometimes the bus has actually been running, it just hasn't tracked.

Regarding the 82 not tracking, I believe it's a mistake on their end, where the ability to track the bus wasn't selected when publishing the timetable, something very similar to when Borders Buses first took over the 418 & it took about a year for it to finally track as the '0418' for some reason.

Obviously the PVR will increase by 2 on Monday with the 599, so one would hope they have a contingency plan to ensure that they are not going to end up not running services for the full day or indeed taking a bus from the 520 to do a 71...
