How can the new LEGO pneumatics be used for trains? LEGO came out with new pneumatics. Since I'm a train guy (my wife is more into technic and already saving money for the Mercedes ;)) I was wondering, how could we apply the new things for Trains?!
The first thing that came up in my mind when reading your question is: operate switches on your track using pneumatics. You'll require a lot of hose, and would need to experiment a bit with how long the tubes can be without losing too much pressure, but the actuators could operate the switch handles easily, and you can route the hoses under buildings or even under your train table.
