Train Power

Ways to power a train

There are several ways to power a locomotive. All these power sources are able to power a locomotive but most have consequences.

First there is steam. It works by creating heat, usually by burning something e.g. wood, coal. That heat turns water into steam which is used to push the pistons and drive the train. But the smoke that comes out is dirty and the soot goes everywhere.

Diesel power, it works by an internal combustion engine powering up a generator which through electric currents turn the wheels. But it pollutes a lot.

Electric is a clean power source. Electric trains gather electricity from an overhead wire, then that electricity powers the motors that move the trains. The only drawback is that it is expensive.

The final way to power a train is magnetic levitation or maglev. It uses magnets that repel each other to make a space between the ground and the train. There is no friction in this for of powering the locomotive meaning it can go faster then any other form of powering a train. The only drawback is that it also is expensive.
