A locomotive, also known as an engine, is a self-propelled vehicle that provides the motive power for a train. It is used for hauling railroad cars on tracks and includes the machinery to generate power and transmit it to the driving wheels. The word "locomotive" comes from the Latin loco from a place, ablative of locus place, and the Medieval Latin motivus causing motion.
Some key features of locomotives include:
-
Wheel arrangement: This refers to the number and arrangement of wheels on the locomotive. Different wheel arrangements are used for different purposes, such as speed, power, and stability.
-
Classification: Locomotives are classified based on their wheel arrangement, type of fuel used, and other factors.
-
Types: There are various types of locomotives, including steam, diesel, and electric locomotives.
-
Usage: Locomotives can be used for different purposes, such as hauling freight or passenger trains, shunting, or relocation.
It is important to note that a locomotive is not the same as a train. A train is any vehicle that runs on guide rails, while a locomotive is a specialized type of train car that is used to run the whole train.
