TJ, we all want an integrated transport system but its ridiculous because you seem to think anything is possible when in fact there are a lot of constraints associated with what you want which have already been outlined above! Yes it would be nice to have everything connected within the same building without having to use stairs or go outside but its not possible at waverley at least. I’m not sure about the airport situation but a little walkway is hardly the end of the world.
There are far greater issues with the tram solution like the fact its nothing more than a glorified bus service and still has to conflict with traffic on cross streets. It will do very little to reduce car trips into the city centre which should be the main aim in my eyes. Trips to and from the airport are small change compared with everyday peak hour commuter trips.
