Neither routes are currently providing valid data. In the Countdown API we’re at least getting “destination = ‘No Information’” and “Direction = -1” for each vehicle on the route but the Unified API (https://api.tfl.gov.uk/Vehicle//Arrivals) is just returning “{}”.
Also 147 168 258 283 309 325 363 381 405 412 460 P12. There may well be others.
Rather oddly, for some routes buses can be seen as having operated on the route during the day, even though no stop-related information is being returned. There seems to be a cut-off pojnt, differing between routes. It looks as if reports suddenly stopped coming in and at that point buses on the road were deemed no longer to be in service.
Many of the routes identified have seen changes today. I would take a wild guess that they all have but some of them may just be stop changes, not affecting the timetable. From afar this looks like a simple failure to load the new schedules.
As my post on that thread explains, something is being reported but the destination field says “No Information”. This seems to be enough to prevent the London Vehicle Finder (and other Countdown-using apps?) from reporting arrivals across the route as a whole but not at individual stops. Seriously weird.
I suspect the issue is that the iBus software that TfL uses to run these systems isn’t very good at being disrupted in this way and can’t make timing changes based on some types of route change (re-routing down a different road) but can deal with others (short running).
While the screen grab above includes reference to diversions, I don’t think that was the problem here. As far as I can see it affected all the known changes from last weekend, including the 414, where the only change was a cutback from Maida Hill to Marble Arch and is not, I think, subject to any diversions. It may have affected a few more routes as well but I strongly suspect that they will turn out to have minor operational changes such as changes to driver duties. Unfortunately I cannot confirm that because the working timetable update went wrong and has still not been corrected.
