Skylink

The old Airport transportation was called The TrAAin.
It was so bad that it is surprising that airport officials would come up with such a better system.
The Skylink is awesome.
It is totally automated, and as simple as boarding an elevator.
There are trains running in both directions on their own tracks.
I don't know all of the details, but it looks like the Trains are totally symetrical, so tht they can be used on any track.
If I have time I usually try and take a complete circuit.
The train has a great view, and the you can make the entire trip including stops in around 10 minutes.
Here is a hurky jerky video.
