Metro stations are public transportation hubs where trains operate on underground or elevated tracks. They provide access to urban transit systems, allowing passengers to travel quickly and efficiently within a city. Each station typically features ticketing areas, waiting platforms, and signage to guide travelers. These stations are designed to accommodate large numbers of commuters, often including amenities like shops and restrooms. They connect various neighborhoods and can link to other forms of transportation, such as buses or trams, enhancing the overall public transportation network in a city.
