I think that's the key to it - doing the trip in enough less time than driving in order to act as an incentive to change from driving to the train. Actually you already have the best chance on the main south out of all the lines, if you use the two through Southern Highlands trains. They do the trip between Bowral and Central in 1:50 min to 2:00 hrs, compared to about 1:30 min driving - which would spin out to well over 2 hrs in peak, plus the issue of finding parking.BroadGauge wrote: I'd be happy if the Southern Highlands line simply took the same amount of time as driving does!
I haven't ridden an ICE train (not sure that I'd want to after reading the details of the Eschede disaster and the lax culture at DB), but I've done the Nuremberg-Munich route a number of times by both train and car. For a lot of the time the two routes are right beside each other and you sit in the car doing about 130, being passed by BMWs/Mercs/Audis doing 200, that are paralleled by the stopping trains doing a little under 200 (double deck push-pull trains with an electric loco) and then the occasional ICE shoots past at 300. Quite honestly I was happy with the stopping trains that, by Australian standards, had astronomical speed and great acceleration on their own, plus the ability to get on an off at intermediate towns if you're weren't doing the full length. What Gladys mightn't have picked up about the ICE is that is an intercity train that bypasses a lot of places on the way - not what you want on a NSW interurban or regional train. That would be a high-performance (as opposed to high speed) train with good acceleration (stop-start ability) and a maximum speed of probably no more than 200.
