A rail system is a network of tracks and trains designed for transporting passengers and goods. It typically consists of various components, including locomotives, railcars, and stations. Rail systems can be found in urban areas, where they serve as public transit, and in rural regions, where they facilitate freight movement. Rail systems can be powered by different sources, such as electricity or diesel fuel. They are known for their efficiency and ability to move large volumes of cargo over long distances. Many countries invest in rail infrastructure to enhance connectivity and reduce road congestion.
