Traditional trains are vehicles that run on fixed tracks, typically powered by steam, diesel, or electricity. They consist of a locomotive, which provides the power, and several cars that carry passengers or freight. Trains have been a vital mode of transportation since the early 19th century, connecting cities and facilitating trade. The design of traditional trains includes wheels that fit into rails, allowing for smooth travel over long distances. They are often associated with iconic elements like train stations, railroad crossings, and passenger cars. Trains have played a significant role in the development of modern infrastructure and continue to be an important part of public transport systems worldwide.
