Berlin Brandenburg Airport (German: Bahnhof Flughafen Berlin Brandenburg) is a future railway station located under the terminal of Berlin Brandenburg Airport, Germany. The train services will be operated by Deutsche Bahn. The station is located in a 3.1 km long tunnel, on a branch of the Berlin Ringbahn, in the municipal territory of Schönefeld, just outside Berlin. It will replace Schönefeld as the airport station after the merging of Berlin Schönefeld Airport into the new airport.
Due to delays in the construction of the airport it is not yet known when the airport will open, possibly in 2015. The station will be served by Berlin S-Bahn, Regional-Express, EuroCity and Intercity-Express services. The station lies directly under the airport terminal and has six platforms. Two of these are terminating platforms for the S-Bahn lines S45 and S9.
