What is "ringzug"

The Ringzug (“ring train”), also called the 3er-Ringzug (“ring train of the 3”) is a passenger transport network in the districts of Tuttlingen, Rottweil and Schwarzwald-Baar in southern Baden-Württemberg, Germany. The Ringzug went into regular operations on 31 August 2003 and has operated in its current form since 12 December 2004. The concept of the Ringzug is the operation of a clockface timetable, coordinated with a variety of other buses and train services, over an S-Bahn-like network in a rural environment. In March 2006, the passenger association Pro Bahn described the Ringzug as an exemplary public transport system at its 2006 passenger transport awards (Fahrgastpreis 2006). The Ringzug has aroused interest beyond the region and can point to steadily rising passenger numbers and declining deficits.
