A railway system is a network of tracks, trains, and stations designed for transporting passengers and goods. It typically consists of rail tracks, locomotives, and rail cars that run on fixed routes. Trains can be powered by electricity, diesel, or steam, and they connect various locations, making travel efficient and convenient. Railway systems are essential for economic development, as they facilitate trade and mobility. They can be found in many countries, with notable examples including the United States rail network and the Shinkansen in Japan. These systems help reduce road congestion and lower transportation costs.
