Rocky Mountain Zephyr

You are the last passengers left aboard the Rock Mountain Zephyr. The train crew has mysteriously vanished and the train is barreling down the track at an alarming rate of speed. In one hour the train will reach High Point Curve. A train going that fast would surely jump the rails and plummet down the cliff. You must make your way to the locomotive cab and figure out how to stop the train before it gets there.
