The S10 was a line number used by the Berlin S-Bahn from June 1991 until December 1999. The line operated solely in the former East Berlin and was replaced by the S8 for the northern part of the route and the S47/S9 for the southern routing. History Originally, the S10 ran from Oranienburg to Schönefeld International Airport when line numbering was introduced to former East Berlin lines in June 1991. With the re-construction of the direct line between Frohnau and Oranienburg for the S1, the S10 terminated at Birkenwerder from May 1992. The line was redirected to Spindlersfeld from Schönefeld International Airport in May 1993, which remained the routing until the line was withdrawn in December 1999.
