Hmm... seems like they changed from CC-BY back to a custom license?

I'm not sure whats wrong with keeping historical records...

In my view, the less restrictions they place on the data, the more
freely it will flow, creating more competition and innovation among
people using the data and building products incorporating the data...

Yeh, I believe the data is,
* stops as nodes (so bus stops, train stations, ferry terminals)
* distinct journeys

Probably worth another look though, but I believe,
* It didn't say which roads were used for the route, just station to
station (but since the stations are fairly close you could infer)
* I don't think it used the common route names, but rather each
timetabled journey was recorded as a separate route.

You can still include this into OSM, its just you need to decide is it
better to do a mass import, or collect it naturally via the traditional
OSM way of going out and observing what is out there.

See http://tianjara.net/data/tdx.nsw.gov.au/. Mind you I haven't looked
any further into it since my initial investigation.
