Can a train fall off the tracks?

Thus, trains stay axled, with the wheels on both sides of the train rotating at the same speed, and are still able to go around curves. With all this tilting, it’s surprising that trains don’t fall over. Even moreso, the wheels of a train are small compared to the height, speeds, and momentum of trains.

Do trains have differentials?

Trains however do not have differentials. If they did, there would be a risk of them falling off their tracks! Trains have fixed wheelsets, but still must navigate turns.

How are train wheels connected?

The wheels on each side of a train car are connected with a metal rod called an axle. This axle keeps the two train wheels moving together, both turning at the same speed when the train is moving.

How do train wheels work?

Here is an exaggerated view of a train wheel sitting on a track. For a straight track, the two wheels should be at a position such that the radius of the wheel at the contact point is the same. This means that the two wheels rotate the same amount and also travel the same distance. The axle goes straight and stays on the track.

How do trains stay on the tracks when they turn?

As a result when a train is turning it is momentarily running on wheels that are effectively two different sizes. As the outside wheel’s circumference becomes larger it is able to travel a greater distance even though it rotates at the same rate as the smaller inside wheel. The train successfully stays on the tracks!

What keeps the wheel on a train from wearing out prematurely?

They answered the question: What keeps the wheel on a train from wearing out prematurely. The answer is the very clever conical shape of the wheels which allow the outside wheels to turn faster than the inside wheels. The answer to the question posed is clearly: the flanges keep the train on the track.

Do train wheel shapes affect their ability to stay on track?

The train successfully stays on the tracks! In this activity you will test for yourself how train wheel shapes impact their ability to stay on track. At least four plastic or Styrofoam cups of the same size. (The cups should not have a raised edge at the top.) Take two cups and tape them together with their bases facing each other.
