 When Rixdorf became Neukölln in 1912, the line became the "Neukölln-Mittenwalder Eisenbahn" (Neukölln - Mittenwalde Railway).During World War II the Mittenwalde line was heavily used for transporting both munitions and passengers, reaching a peak of over 1 million tonnes and 3 million passengers in 1942/43.The Hermannstraße S-Bahn station was not damaged during the bombing of Berlin, but the entrance was severely damaged during the Battle for Berlin and that stretch of the Ringbahn was closed from April 1945 until 18 June 1945.
