Why do trains oscillate?


Why do trains oscillate? Summarising from the article: the vibration arises because the track is not completely smooth and the train wheels are not perfectly circular. As the train moves along thetrack, the result is an oscillating force at each wheel/track contact, and this is transmitted to the ground at each sleeper/ground contact.


Is it normal for a train to sway?

Commuter trains tend to rock and stop frequently. Double-decker trains can be great for viewing scenery, but also tend to sway. Higher-end bullet trains can ride quite a bit more smoothly but then no train is considered completely free of motion sickness triggers.

How do trains not hit each other?

Trains cannot collide with each other if they are not permitted to occupy the same section of track at the same time, so railway lines are divided into sections known as blocks. In normal circumstances, only one train is permitted in each block at a time. This principle forms the basis of most railway safety systems.


Why do train wheels not slip?

To help the wheels stay on the track their shape is usually slightly conical. This means that the inside of the wheel has a larger circumference than the outside of the wheel. (They also have a flange, or raised edge, on the inner side to prevent the train from falling off the tracks.)


Can you feel a train coming?

Different tracks have different amounts of vibration at different frequencies. And of course high speed routes even if you could feel them you may still not have time to get out of the way before a train obliterates you. So in some cases you'll feel the vibrations before the train comes and in others you may not.


Why do trains make noise at night?

Trains have the right-of-way because they cannot quickly stop for a motorist at crossings or for trespassers on the tracks.
