Höyryvetureille

Höyryvetureille refers to the plural form in Finnish for "steam locomotive". A steam locomotive is a type of railway locomotive that produces its pulling power by means of a steam engine. The engine burns fuel, such as coal, wood, or oil, to heat water in a boiler. The steam generated in the boiler is then directed to cylinders, where it pushes pistons. These pistons are connected to the locomotive's driving wheels, causing them to rotate and propel the train forward.

Steam locomotives were the dominant form of railway motive power for over a century, from the early 19th century until the mid-20th century. They played a crucial role in the industrial revolution, enabling the rapid transportation of goods and passengers. Their distinctive appearance, with large boilers, tall smokestacks, and often elaborate detailing, has made them iconic symbols of the railway age.

While largely replaced by diesel and electric locomotives due to their higher efficiency, lower operating costs, and reduced environmental impact, steam locomotives still hold a significant place in history and popular culture. Many preserved steam locomotives are operated on heritage railways for tourism and special events, allowing enthusiasts and the public to experience the power and romance of these historical machines. The term "höyryvetureille" would be used when referring to multiple steam locomotives collectively.
