Gotha (Straßenbahn Gotha/Thüringerwaldbahn), above ground tramway (24 km long), in existence since 1924, to Waltershausen, Friedrichroda and Tabarz
The S-Bahn routes all feed into one of three core lines: a central, elevated east-west line (the Stadtbahn), a central, mostly underground north-south line (the Nord-Süd Tunnel), and a circular, elevated line (the Ringbahn).
The area mostly hit did not include railway main lines, which were more northern (Stadtbahn) and southern (Ringbahn), but two terminal stations of Berlin (Anhalter and Potsdamer Bahnhof, the latter of which was already out of service since 1944 due to bomb destruction).
The cities of Bochum, Castrop-Rauxel, Dortmund, Duisburg, Essen, Gelsenkirchen, Herne, Mülheim an der Ruhr, Oberhausen, Recklinghausen and Wattenscheid founded the Stadtbahngesellschaft Ruhr in 1969 for coordinating the plans to transform tram routes into Stadtbahn routes.
Since 1997, the line has been operated as part of the Saarbahn Stadtbahn service; Regional-Express services also run between Saarbrücken and Strasbourg.
The Stadtbahn is part of the regional transport cooperative, the Transit and Tariff Association Stuttgart (VVS), which coordinates tickets and fares among all transport operators in the metropolitan area.
After the re-opening of the Berlin Stadtbahn in 1998, Regional-Express and long-distance services of the Stadtbahn ran over this route especially towards Stralsund.
