my hubby is doing training in the city at the moment, commuting from Baulkham Hills. He can walk to the bus stop (10 minutes), so there is no issue with parking, and he needs to be in the city by 9am. He is leaving home at 7.30am and getting in with plenty of time. On the first day, the bus was in the city in just over 30 minutes, which was very surprising!
I think the trip home is taking longer, but still only around 1 hr.
He is able to leave much later to get the bus to the city than he does to drive to Chatswood.
In terms of the Hills, I would still buy in Baulkham Hills over Seven Hills for a PPOR any day, even though there is no train. I think its a much nicer area.
With Carlingford and North Rocks, you need to check the drive to get onto the M2. Pennant Hills Rd can be a nightmare, and it may take you longer to get onto the M2 than it does to drive the extra distance on the M2. and if you use Epping Rd instead, from Carlingford you have to cross the Epping railway bridge, which can take forever.
and of course, you can do what most of us do and shift workplaces to somewhere local. There are so many companies in Norwest Business Park that it should be possible to find something local!
cheers
