How do trains stay on the track?

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.)

The outer rail is raised to tilt the train to the inside of the curve - this provides roll-over protection and at cruise speeds gravity helps keep the train more or less centered in the track. The wheels are tapered and 'steer' the bogies away from the rails, so on a curve the train is 'steered' around the bend.

A derailment of a train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes.

The wheel bevels are specifically designed so that when the train goes around a corner it stays on the tracks. The wheels that have to travel a greater distance have a greater diameter, and everything stays aligned. The end result is a train that stays on the tracks.

Fact #8: Trains Travel in Both Directions Tracks aren't one way, so even if you've seen a train traveling east, a train could travel west on the very same track.

Do trains drop waste on the tracks? Not anymore. In the US until the 1960's, some toilets emptied directly onto the tracks. A sign was posted over the toilet reminding passengers not to flush while the train was on the station.

Can A Penny Derail A Train? Though a penny or some other coin is extremely unlikely to derail an entire locomotive, the act of doing so is illegal. In fact, it's illegal to place or throw any small or large object on a railroad track.

Federal data from 2021 and 2022 says an average of about three trains derail in the U.S. a day. While not all derailments are equally as dramatic or dangerous, railroads are required to report any derailment that causes more than $10,700 in damage.

The traditional method of disposing human waste from trains is to deposit the waste onto the tracks or, more often, onto nearby ground, using what is known as a hopper toilet. This ranges from a hole in the floor to a full-flush system (possibly with sterilization).

One of the reasons trains need to back up is to the couple and decouple the cars that it pulls. Another good reason is that it is sometimes difficult for the train to turn around. There are of course other reasons. A train will go forward and back when it is occupying a crossing and stops on its tracks.

Standing upon (or making bodily-contact with) both wheel-rails of a railroad line simultaneously would almost-certainly not result in a life-threatening (nor even mild) electrical-shock of any sort (they are grounded and almost never carry any more than a few stray, harmless volts of electricity, if any).

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.
