30 by train
It takes me a good 40-45 minute drive to Unley where I work so it would take at least 50-55 minutes in peak hour . Some horrible days last year with the road blockages due to the Expressway roadworks and no train sometimes it took an awful 1hour 20 mins to get to work :(
My experience as well, 30 mins in non-peak hour, a good 45 mins in peak hour
it can take up to 45 minutes if their is a lot of traffic, but only about 30 in quieter times.
