In the spring of 2007, the privately owned Rhein-Sieg-Eisenbahn (RSE) formed a joint venture to operate the Nuon plant of the Chemiepark Oberbuch, which required a train driver of the RSE and a shunter from Nuon to work together in shifts at the Oberbruch site. A diesel locomotive of the RSE was used, rather than a fireless locomotive. The reason for this was that the fireless locomotive of the "Meiningen" class, which had previously been used for shunting, had been taken out of service at a major examination. Under this new collaboration, the Chemiepark Oberbuch hoped for "greater flexibility, contacts with new customers and greater use of rail operations."
