The Grünau Cross–Berlin Brandenburg Airport railway is a railway line in the south of Berlin, the capital of Germany, and in the adjacent areas of Brandenburg. It is used by the Berlin S-Bahn. The first, 5.9-kilometre-long (3.7 mi) section was opened in 1962 and served mainly as a connection to Berlin Schönefeld Airport and the associated long-distance station. In 2011, a 7.7-kilometre-long (4.8 mi) extension went into operation to connect with Berlin Brandenburg Airport (BER). Due to delays in the commissioning of BER Airport, this section has only been used for public transport since October 2020.
