It is operated by Transdev Rheinland GmbH as a subcontractor of Regiobahn Fahrbetriebsgesellschaft mbH (Regiobahn for short), who is the PSO operator on behalf of Verkehrsverbund Rhein-Ruhr (VRR).
The line is operated using Integral S5D95 DMUs at 20-minute intervals,[2] with only two trains an hour running between Mettmann and Wuppertal.

The planned electric Stadler FLIRT trains have already been built, and are currently used by Abellio Rail NRW on other lines of the Rhine-Ruhr S-Bahn.
