 The BAR is still heavily used by freight trains, both serving the Seddin marshalling yard (south of Potsdam) and for trains between western Germany and Poland.Between October 1899 and December 1965 (passenger) and October 1967 (freight), trains ran from Groß Kreutzstation on the 12 km long light railway to Lehnin via Nahmitz.Significant volumes of freight formerly ran over the originally private Brandenburg Towns Railways ("Brandenburgische Städtebahn") to and from Brandenburg, which in turn connected near Brandenburg station to a formerly extensive network of sidings to the Philipp Weber iron and steel works and the city's port.
