How Do Trains Stay On The Track?

I bet most of you reading this article thought this must have a fairly simple answer. You may have had started theorizing about the wheels and how they might have a little edge guard to keep them straight. Maybe you reasoned they might have a shallow groove that makes them stay lined up on the rails. After all, those ideas do make sense if we assume the train is going down a straight track.

What if a train has to turn?

Try walking in a circle. If you do, you will notice your outside leg will be taking bigger steps and moving farther than your inside leg. Obviously, for anything to turn, one side will need to move farther than the other. Now you are probably thinking back to your previous ideas and how they would need to be modified in order for the train to actually turn.

Maybe it is like a car and uses a differential to make the left and right wheels spin at different rates. However, that is not the case. The wheels are both connected by a solid metal bar. So with this in mind, how does a train stay on the tracks?

My guess is most of you are still stumped. I certainly was when I was asked these questions.

The answer is surprisingly simple. The wheels are slightly tapered and they shift over when turning which allows the outside wheel to rotate around a larger diameter than the inside wheel. Then the wheels shift back to the center when the track straightens out.

Here is a visual example:

18 Things I Want To Do Now That I'm 18

I'm technically an adult, so I'm legally required to live a little, right?

For the entirety of my high school career, I was always seen as the goody-two-shoes. I never got in trouble with a teacher, I kept stellar grades, and when I wasn't doing extracurricular activities, I was at home studying. Even when I did go out, it was usually with a bunch of fellow band geeks. The night would end before 11:00 PM and the only controversial activity would be a fight based on who unfairly won a round of Apples-to-Apples when someone else clearly had a better card (I promise I'm not still holding a grudge).

Now that I'm officially an adult, I want to pursue some new things. I want to experience life in a way that I never allowed myself to do prior to entering college. These are the years that I'm supposed to embark on a journey of self-discovery, so what better way to do that than to create a bucket list?

So, maybe you could answer them for me, and if not then we can both wonder what the answers to these 15 questions could be.
