Chennai Central Railway Station, built in 1873, is one of India’s most prominent railway hubs. Designed by architect George Harding, it features a striking Gothic-Revival style with red brickwork and a tall clock tower. Initially constructed to connect Chennai with other parts of British India, it has since evolved into a major transit point for South India. The station serves both long-distance and suburban trains, handling millions of passengers annually. Over the years, it has undergone multiple renovations while retaining its historic charm, making it an iconic landmark of Chennai.
