Pneumatic turnout control...the early daze using Freon 12...

Back in the early days of model railroading, there was an ongoing effort to come up with an effective method of using air to throw switches, just like the real roads did.

Being an EPA certified refrigerant handler, you can imagine my amusement at the thought of using Freon 12, an ozone depleting product, as a propellent for model turnouts...but then again, some of these guys were using stove black for paint and powered asbestos for scenery...
