The largest hand-wound clock mechanism in New England is at South Station

South Station is a railroad terminal located at Dewey Square in downtown Boston, Massachusetts. Constructed in 1899 to replace earlier terminals with a union station, it is the busiest railroad station in Greater Boston. It is New England's second-largest transportation center after Logan International Airport. Along with North Station, it is one of two Boston terminals for the MBTA Commuter Rail system and Amtrak intercity rail service.

The South Station Bus Terminal is located above the platforms, and the adjacent subway station is served by the Red Line and Silver Line of the MBTA subway system. A major renovation of the station, including the construction of accessible platforms, took place from 1984 to 1989. The bus terminal opened in 1995.

The Classical Revival structure was designed by Shepley, Rutan and Coolidge. The station's head house and wings incorporate Neoclassical architecture with a stone façade made from granite from nearby New England quarries. The clock on top of the main head house is the largest operating hand-wound clock mechanism in New England, weighing over 400 pounds. The classically styled stone eagle that sits atop the clock is 8 feet wide and weighs over eight tons.

The curved shape of the building facade pushes its presence into the surrounding area. Two works of public art are located inside South Station as part of the Arts on the Line program: Destinations (1995) by Jeffrey Schiff, consisting of 25 cast iron spindles hanging from the ceiling of the entrance foyer, and Musclebound for Miami (1991) by Mayer Spivack, a 4,000-pound sculpture made from Type H railroad couplers.
