Seaboard Coastline Building, also known as Old City Hall, is a historic train station located at Portsmouth, Virginia. The original section was built in 1894-1895 by the Seaboard Air Line Railroad. It is a five-story brick and concrete structure, with the top two floors added in 1914. The front facade features a distinctive half-round or semicylindrical profile intended to recall the imagery of the streamlined locomotives of the late-19th century. The building served as the northern terminus and office headquarters of the Seaboard Air Line until 1958, then used as the municipal building until 1980.
