used depending on the demand, but since 2011 only trains with two double-deck carriages have operated on this line. Around two million passengers were counted on the line in 2005 and it was 2.8 million in 2010. Until the timetable change on 30 May 1999, the S 2 service operated on the Dresden Hbf–Radeberg–Arnsdorf (b Dresden) route. These S 2 services reversed in the Arnsdorf (b Dresden) carriage train to continue as Regionalbahn services to Kamenz, Görlitz or Zittau. It was at that time the only S-Bahn line that was operated with diesel-hauled push-pull trains. Line S 3 The S 3 service runs on the Dresden–Werdau railway from the Hauptbahnhof towards Chemnitz. It passes through the Plauenscher Grund ("Plauen ground"), the deep valley of the Weißeritz between Plauen and Freital. From Freital it runs in the valley of Wilde Weißeritz to Tharandt. The line was almost completely destroyed by August 2002 floods. After it had been put back into operation after the flood damage had been repaired at the end of 2003, around 2,300 passengers per day were counted. Inside Dresden, the next stop on the S 3 after the Hauptbahnhof is Dresden-Plauen station. In Freital the S-Bahn line serves large parts of the populated areas.

Next to the Freital-Deuben station, there is a bus station with connections to ten regional and six local bus routes. The railway line runs along the traffic axis of the town, which is also serves as the main axis of Freital's bus routes. Typically, sets of two double-deck carriages are used. Until the timetable change in May 1995, operated S 3 as S 5. Between 9 December 2007 and 11 December 2010, it operated as a supplementary line to S 3, line S 30 and since the timetable change on 12 December 2010, the entire line between Dresden Hbf and Freiberg has operated as S 3. It normally begins and ends in Tharandt, but it serves the stations of Edle Krone, Klingenberg-Colmnitz, Niederbobritzsch, Muldenhütten and Freiberg (Sachs) running to Freiberg from Monday to Friday in the morning peak and from Freiberg in the afternoon peak. It is the only Dresden S-Bahn line that runs outside the area of the Upper Elbe Transport Association. Between Niederbobritzsch and Freiberg the fares of the
