The story
RNV was established on 1 October 2004 as a joint subsidiary of the five principal public transport operators that had previously operated in the region:
the Heidelberg Tramway (Heidelberger Straßen- und Bergbahn, HSB),
MVV Transport (MVV Verkehr, the operator of trams and buses in Mannheim),
the Upper Rhine Railway Company (Oberrheinische Eisenbahn, which became part of the MVV Group in the early 2000s and was then known as MVV OEG),
the operator of the Rhine-Haardt Railway (Rhein-Haardt Bahn, RHB) and
Verkehrsbetriebe Ludwigshafen (the operator of buses and trams in Ludwigshafen, VBL).
RNV is a public sector operation, as its ultimate beneficial owners are local authorities in the region.
Since 1 March 2005, RNV provides transport services on behalf of its parent companies. Fares are set by the local passenger transport executive, Verkehrsverbund Rhein-Neckar (VRN).
