Blankenfelde station is on the Berlin–Dresden railway in the locality of Blankenfelde in the municipality of Blankenfelde-Mahlow in the district of Teltow-Fläming in the German state of Brandenburg. The station consists of two sections that are structurally separate from each other. One section is located just south of the Karl-Marx-Straße level crossing and consists of an island platform for regional and long-distance services. The other section lies north of Karl-Marx-Straße and is the southern terminus of Berlin S-Bahn line S2. On the official S-Bahn maps its name is styled Blankenfelde (Kr. Teltow-Fläming) to avoid possible confusion with Blankenfelde locality in the Pankow district in northern Berlin.
