Subway (Metro)

A subway (metro) is a rapid transit train system used in urban areas to transport large numbers of people efficiently within a city. It consists of underground and above-ground tracks with trains running on fixed routes. Subways are designed to provide quick, reliable, and frequent service, helping reduce traffic congestion and connect various neighborhoods and districts. They typically operate on dedicated tracks separate from surface traffic, enabling faster travel times even during peak hours. Subway systems are an essential part of urban infrastructure, supporting daily commuting and enhancing city mobility.
