History

A southern extension from the former terminus at the Schönefeld Airport station has been constructed prior to the opening of the new Berlin Brandenburg Airport. The rail extension includes two new stops: Waßmannsdorf and Berlin Brandenburg Airport. Due to the opening of the new airport, Schönefeld Airport station has been renamed "Flughafen BER - Terminal 5 station". When Terminal 5 was closed, the station has been renamed Schönefeld (bei Berlin) station.
