Until 2010, the southern section was served by the "Loreley-Bahn" (RB 10) and the "Loreley-Express" (RE 10) services, using electric class 143 or 110 locomotives and 4-5 coaches every one or two hours. In 2007, the operation of services on the section from the Koblenz–Frankfurt section was tendered by the Rhein-Main-Verkehrsverbund (Rhine-Main Transport Association, RMV) and the "Zweckverband Schienenpersonennahverkehr Rheinland-Pfalz Nord" (Association for Passenger Rail Transport of Rhineland-Palatinate North). On 12 December 2010, VIAS GmbH took over operations of the service, now called the "RheingauLinie" (originally numbered SE 10, but called RB 10 again from December 2016). Between Koblenz, Lahnstein and Wiesbaden trains now stop at every station, but between Wiesbaden and Frankfurt Central Station there now only two stops. Similarly, between Neuwied and Koblenz Central Station there were initially no stations. Since its completion in April 2011, Koblenz Stadtmitte station has also been served. The services run every hour, sometimes even every half-hour. VIAS GmbH uses new Stadler FLIRT sets for the service. Because of the renewal of track on the line in 2010 and the good acceleration of the FLIRT sets, the travel time is only slightly longer than that of the former RE 10 service, which did not stop at each station.
