Locomotives are a type of engine used for transportation, typically on railways. They are also known as ENGINES or iron horses due to their power and strength. The term locomotive is derived from the Latin word loco, meaning 'to move, ' and motives, meaning 'causing motion.' Locomotives have been used since the early 19th century and are still in use today. They are powered by steam, diesel, or electric motors and can be used to pull or push cars and other vehicles. Locomotives are an important part of the transportation industry and are essential for the efficient movement of goods and people.
