The current station is the third on the site. Though technically a
union station, which is a station used by several railways, it was never identified as such in publications such as the Official Guide of the Railroads and Steam Navigation Lines or Pennsylvania Railroad Timetables. The first two stations were shared by the
Pennsylvania Railroad (PRR),
Reading Railroad,
Northern Central Railway (NCR), and the
Cumberland Valley Railroad (CVR). The third and current station excluded the
Reading Railroad, which built its own station in 1856, and the CVR maintained a small
depot adjoining the much larger NCR/PRR station. The CVR station was razed sometime in the late 1960s or early 1970s. The Reading Railroad discontinued passenger service into its Harrisburg station in the 1950s and its station was torn down in the early 1960s to make room for a new post office; however, it continued passenger service on the
Queen of the Valley. The last northbound train bound for Sunbury, Williamsport and Buffalo was the
Penn Central's unnamed successor to the
Buffalo Day Express, ending in 1971. The last Erie-bound PRR trains were in 1965 before the
Northern Express and
Southern Express were diverted to Buffalo. The current station was built by PRR in 1887 and significantly rebuilt with its distinctive barn roof in 1905 following a serious fire in 1904. It was listed on the
National Register of Historic Places in 1975, and is also designated as a
National Historic Landmark. The station is one of the few railway stations in the United States that still has a
train shed above the tracks. It also has a red
brick exterior, unlike many of the still-used U.S. railway stations built slightly later in the early 1900s that have white stone facing, including
30th Street Station in
Philadelphia and
Washington Union Station in
