What's the plan for Reconnecting Rail?

There's been a lot of talk over the past couple of years about the need for a commuter rail service between the Adelaide Hills and the metropolitan area.

On the surface the idea sounds like a good one.  Get cars off the freeway, and give people a stress-free way to get to work on convenient public transport.

But when you start to think about it, all sorts of problems arise, from where to put the track, to how we'll get from our homes to the closest railway station.

One person who's thought a lot about these problems is Douglas McCarty.  His career has given him an unique insight into the issues and the solutions, and he thinks he has a plan that could see us all catching trains to town within five years.
