The S6 was a line number used by the Berlin S-Bahn from June 1991 until June 2002. The line always ran to the south-east corner of Berlin, although a number of routings were used during its period of operation. The line was replaced by the S46 and S8 which now provide connections to south-east Berlin. History The first routing of the S6 ran from Charlottenburg to Königs Wusterhausen from June 1991. A year later, the line was extended by one station to Westkreuz. In May 1994, the line was shortened to act as a peak-time shuttle between Warschauer Straße and Zeuthen. The line was removed in June 2002. Route The station listing below provides an overview of what the line looked like.
