A subway is an underground train system used for public transportation within cities. It is designed to carry large numbers of passengers quickly and efficiently, especially in busy urban areas. Subways usually have multiple stops along fixed routes, allowing people to travel between different parts of the city without being affected by surface traffic. These trains are typically faster than buses and can handle high volumes of passengers during rush hours. Subways are often a preferred mode of transport in cities with heavy traffic or limited road space.
