S-Bahn Erfurt was a colloquial term for a railway connection that existed from 1976 to 1993 in the Thuringian state capital Erfurt, Germany. The term "S-Bahn" is also occasionally used in popular literature. Other contemporary media used terms such as "suburban traffic at the local transport tariff" to describe it. When the line was introduced in 1976, only the "reversible train service" on this line was highlighted as a special feature. In the Kursbuch tables of Deutsche Reichsbahn, the terms "S-Bahn" or "S-Bahn-Tarif" were not used for this line. Riethschleuder was another colloquial term for the connection. Route description Starting at Erfurt Hauptbahnhof, the line ran in a semicircle north and east around the city centre. It used the route of the Wolkramshausen-Erfurt railway line as far as Erfurt Nord station. There it branched off to the west and, using the route of the former Erfurt–Nottleben light railway, developed the new development areas in the north of Erfurt. The four stations served were the stations Erfurt Hauptbahnhof and Erfurt Nord which still exist today, the former stop Erfurt Györer Straße and the former terminal Erfurt Berliner Straße station. The journey time over the entire route was 13 to 14 minutes. Operation and history The construction of the new Rieth development area in the north of the city of Erfurt made it necessary to connect this part of the city to the city centre. The existing Erfurt tramway and the supplementary bus lines offered by the Erfurt public transport companies (Erfurter Verkehrsbetriebe) were no longer able to meet the growing demand for transport at peak times. Since the track of the former small railway to Nottleben ran directly through the residential area, a plan was drawn up to set up a railway connection between the north of the city and Erfurt's main railway station (Hauptbahnhof) in order to relieve the urban local traffic. Since all the tracks were already in place, only two new stations had to be built. Thus, the connection could be opened on 13 May 1976 after a construction period of only three months. The line length was 8.6 kilometres, of which 2.7 kilometres were on the line of the former light railway. In the Kursbuch of Deutsche Reichsbahn, the line was listed under route number 642. There was no interval timetable. The trains operated only during the rush hours. On working days, eight (1985) or nine (1990)
