This article should not be translated from German, because de:S21 (Berlin) describes a planned North-South DC S-Bahn-line, while this article describes the discontinued AC S-Bahn service. In the German wikipedia, S-Bahn services usually do not have an own article. It's just a coincedence that the planned line and the former service have the same name. -- U-Bahnfreund ( talk) 15:15, 3 November 2014 (UTC) reply
