Here’s a Journey Planner oddity. Select a direct bus journey from Fairfield Halls to Norbury Station on a Sunday and I am offered route 109, boarding at stop KC.
Same thing on a Monday to Saturday and I am advised to walk to Park Street in order to catch the 109.
I had a look at the Datastore XML file for the 109 and, sure enough, the file shows this dichotomy between Mon-Sat and Sunday operation. There is also an oddity in the Journey Pattern Sequence section of the file where the field which should order the stops in each direction suddenly becomes blank at exactly the point at which Fairfield Halls appears for the first time (about 5,200 rows in).
On the face of it this looks like an incorrect file driving Journey Planner, rather than a reflection of reality and even if the route does go a different way on a Sunday, this should not, I imagine, be any reason for the stop sequence numbers to disappear in this way within the XML
