Hi! May I ask why you removed the "operator" part? It's there to avoid conflicts with non-English name tags such as name:fr=* and name:de=*. I've also documented it at osm.wiki/Buses#Step_1_-_Add_bus_stops_to_OpenStreetMap based on the discussion at osm.wiki/Talk:Tag:highway%3Dbus_stop#How_to_Map_Multiple_Networks_using_Same_Bus_Stop
