Subways (Metro)

Subways, also known as metros or underground trains, are rapid transit systems designed to transport people efficiently within urban areas. They typically run on dedicated underground or elevated tracks, avoiding street traffic to provide reliable, frequent service. Subways connect key neighborhoods, commercial centers, and transportation hubs, reducing congestion and commute times. They are operated by transit agencies using electric-powered trains, and fare systems usually involve tickets or electronic cards. Subways are an essential part of public transportation, helping cities function smoothly by providing a fast, convenient alternative to driving.
