Thus the Route 601 Beerwah to Kawana thread as a short term measure, which acts as a rail feeder like the 605/615 now. All that is needed is bus and drivers (plus HASTUS driver rostering changes to fit in the new route).
That route gradually shortens (and frequency increases as it gets re-purposed as a local service) as the Baringa/Caloundra stage of the DSCRL opens up, and when it gets to Birtinya, the buses are moved to boost the existing routes servicing and/or terminating at Birtinya/SCUH now.
