While poking around the GTFS-R feeds I’ve noticed that the Metro feed quite often shows per-carriage features that don’t exist - toilets, quiet carriages and luggage racks.
Curiously, while all of those features are potentially present in the new Mariyung sets they are never shown - in fact all of the associated metadata just doesn’t exist. I assume this is because the Mariyung trains share the /v2/gtfs/vehiclepos/sydneytrains/ feed and the feed itself doesn’t know how to present those fields?
