And It Isn't Traveline - Or Is It?
to get started.
... but from today's investigated Journey Planner [JP] we get something quite different.
The 899 is Auntie Frances' Axe Valley service 899, and the X53 is, of course, First Bus.
So who provide this all-operators JP?
For Sheffield, for example, First shows its own journeys on service 120 (Crimicar Lane - Hallamshire Hospital City - Crystal Peaks) but also the overlapping Stagecoach 120 (Hallamshire Hospital - City - Crystal Paks - Halfway)
