There are various types of locomotives designed for different functions. Trolley, Electric and Battery locomotives are examples of locomotives popularly used in today's world. Trolley locomotives are designed for horizontal rail transport especially in mines, to the non-hazardous areas without explosion risks. Electric locomotives range from the small type used in factories and coal mines for local hauling to the large engines used on railroads. Power is collected from an electric trolley, running on an overhead wire or from a third rail at one side of the track. Battery locomotives are used only for local haulage, carry electric storage batteries that act as their primary source of power.

A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit,
When you see an engine running on a railway track without coaches behind it, that is not a train. That is a locomotive traveling on its own. However, when it used to haul the wagons or coaches, the whole unit can be called a train.
A locomotive is any of various self-propelled vehicles used for hauling railroad cars on tracks.
There is still one steam locomotive operating on a Class I railroad in the world For the most part, though, the world has converted to electric and diesel.
The word locomotive originates from the Latin loco – "from a place", ablative of locus "place", and the Medieval Latin motivus, "causing motion", and is a shortened form of the term locomotive engine, which was first used in 1814 to distinguish between self-propelled and stationary steam engines.
A diesel locomotive could cost from $500,000-$2 million. While an electric locomotive could cost more than $6 million. Price depends on whether it is powered by AC or DC traction, how much horsepower it has, or what electronics it is equipped with. A self-propelled vehicle that runs on rails and is used for moving railroad cars.
From the early 1900s, steam locomotives were gradually superseded by electric and diesel locomotives, with railways fully converting to electric and diesel power beginning in the late 1930s.
To begin with diesel locomotives were less powerful than steam engines which meant smaller train sizes (ie. e the amount of carriages they could tow) which you would have thought made them a less preferable option - so why make the switch?
Although commonly called "diesels," the locomotives actually are electrically driven. The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles. Diesel engines are used in many types of vehicles, including locomotives. Diesel engines have a fuel efficiency 20 percent greater thermally than a gas engine.
A switcher, shunter, yard pilot, switch engine, yard goat, or shifter is a small railroad locomotive used for manoeuvring railroad cars inside a rail yard in a process known as switching (US) or shunting (UK).
Oftentimes, the top speed of a freight locomotive is either 65-70 mph, which is commonplace with most modern locomotives
Trains have multiple engines to provide more power to pull the train. Each locomotive has a certain amount of pulling power (called “tractive effort”), which is related to how many horsepower the diesel engine in the locomotive has.
