Formerly used by international passenger trains between The Hague and Cologne, it is now only used by the Maas-Wupper-Express service from Venlo to Hamm via Düsseldorf and Hagen.

This subsidiary of Keolis contracted to operate the RE 13 for 16 years with modern Stadler FLIRT electrical multiple units.

Previously it had been operated by DB Regio NRW with locomotive-hauled push–pull trains consisting of class 111 locomotives and five n-coaches (refurbished Silberling carriages).

Due to lack of approvals for the operation of the FLIRT sets from the German and Dutch regulatory authorities, services initially continued to be operated by locomotive-hauled push-pull trains between Mönchengladbach and Venlo.

Meanwhile, the FLIRT sets ran only to Kaldenkirchen and were supplemented by a short shuttle of class 111 series with three n-coaches to Venlo.
