A propulsion car, usually a locomotive today.
The first trains used people power, horse power, and gravity. Sail power was even tried in the early 1800's in the US. Then steam locomotives, followed by diesel locomotives, followed by electric locomotives, - Today, electric is the most common for passenger trains with diesel the most common for freight trains. Today, some trains distribute their propulsion along multiple cars and don't need a locomotive (referred to as MU, for multiple unit).
Trains are typically powered by electrical energy. This energy is converted into mechanical energy to move the train along the tracks. Some trains may also be powered by diesel engines, which convert chemical energy into mechanical energy.
Very low coefficient of friction.
Trains.
The drive train of an automobile would consist of whatever makes the vehicle move such as engine, transmission, driveshaft, differential(s), axles and so on.
it moves by puttig coal in it

They use freck'in wheels!
By trains, buses & walking!
Diesel trains are louder than electric trains because you the noise that the diesel engine makes, which is louder than the electric engine.
Magnetic trains, also known as maglev trains, use powerful magnets to levitate and propel the train along the track. This technology eliminates the need for wheels and tracks, allowing the train to move smoothly and quietly at high speeds. Unlike traditional trains that rely on friction between wheels and tracks, maglev trains float above the track, reducing wear and tear, and enabling faster speeds and more efficient travel.
It makes them self guiding.
Alas, no. What makes it worse is that very few stations have them either. EDIT: the RER trains have toilets. The metro trains don't.
