of Dresden. Commuter traffic and travel for recreation and tourism are still significant. A few isolated places and hiking areas in Saxon Switzerland can be reached better by the S-Bahn than by bus or car. From Schöna, it runs along the Elbe on the Elbe Valley Railway through the Elbe Sandstone Mountains, through Bad Schandau and past Königstein Fortress to Pirna. There it leaves the immediate bank of the Elbe and runs through Heidenau and southeastern Dresden almost straight to Dresden Hauptbahnhof. It follows a curve through the inner city, crosses the Elbe river and runs after a sharp curve beyond Dresden-Neustadt station next to the Leipzig–Dresden railway. It passes through Radebeul and Coswig, where it branches towards Meißen over the Borsdorf–Coswig railway. The sets of the S 1 consist basically of four double-decked carriages. For larger events and between Easter and Pentecost the trains run with five double-deck carriages. Between Dresden and Pirna were the upgrading of the existing tracks for S-Bahn operations at up to (the first stage of the construction of the Dresden S-Bahn; these tracks are now classified as part of the Pirna–Coswig railway) as well as the construction of two new long-distance railway tracks (for ) were completed by 12 December 2004. On 16 July 2007, the first 16 newly procured double-deck carriages were handed over for the S 1. The trains are equipped with air conditioning, an electronic passenger information system, interior lighting by means of light emitting diodes n as well as sockets at the seats in 1st class. The control cars have 82 seats, the middle cars each have 126 seats. By 9 December 2007, the whole S 1 was equipped with new carriages. From the 2010/2011 timetable change on 12 December 2010, the S 1 services were drawn by locomotives of the class 145. This should result in a four-minute reduction in travel time over the whole route. Since the locomotives do not have sufficient door control for the new double-deck carriages, the trains had attendants the train at each platform. Since the end of 2011, Siemens ES64U2 (class 182) locomotives have replaced the class 145 locomotives. The class 182 locomotives were taken over by DB Regio from DB Schenker and equipped with a local transport package (including a train destination display and side-selective door control).
