Seaboard Coastline Building, also known as Old City Hall, is a historic train station located at Portsmouth, Virginia.

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.

One train was the Portsmouth section of the SAL's full service Silver Comet, bound for Raleigh, North Carolina, Athens and Atlanta in Georgia and Birmingham, Alabama.

[4] The Silver Comet had its last trip into the station in 1968, when the SAL's successor, the merged Seaboard Coast Line, terminated passenger service on the branch leading into Portsmouth.
