    How Trains Turn Without Falling Off the Tracks

    The Science of How Trains Turn Without Falling Off the Tracks



    Have you ever thought about how trains stay on the tracks when they round corners? Trains typically have wheels that are connected together by a fixed axle, meaning that the wheels on both sides of the train always turn at the same speed. This can present problems when turning, because one wheel has to cover more distance than the other.

    Most vehicles solve this problem by decoupling the wheels. In a car, for instance, the left and right wheels turn at different speeds when rounding corners. But that's impossible to do in a train, so how do locomotives stay on a bending rail? The above video by Numberphile explains.

    A little confusing at first but then it makes perfect sense. This is also the same principle that allowed old time sailors to roll wooden barrels of rum up and down two poles suspended from the ship to the dock.

    I learned something too. I always thought it was the wheel flanges that kept the wheels on the track and steered the trains. I never even thought about the speed differential in the wheels going around curves.

    Now you can impress all your friends with your new found knowledge. I doubt anyone else knows how this works either, unless they are a mechanical engineer maybe.
