What is the electric thing on top of trains?

The pantograph is located on the roof of the train and collects the electricity needed to power the train. Since pantographs make direct contact with the overhead power lines in order to obtain electricity, their usage environment is always changing due to the speed of the train and external weather conditions.

Pantographs with overhead wires are now the dominant form of current collection for modern electric trains because, although more fragile than a third rail system, they allow the use of higher voltages.

A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track.

Freighthopping or trainhopping is the act of surreptitiously boarding and riding a freightcar, which is usually illegal.

The majority of modern electrification systems take AC energy from a power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors.

A lot of trains are powered by electricity. The third rail or electrical line running in parallel with the tracks provides power. The voltage of the lines transforms into electrical current through transformers, which power the wheels' motors.

Physically, railroads are composed of at least two metallic (and conductive) rails that run along their entire length. As far as electricity is concerned, these rails act as any other conductor and readily will have a current induced on them from nearby AC power sources.
