On 08.08.2011, the first two SNCB/NMBS EuroSprinter locomotives with automatic couplers (type GF) were transferred to Wegberg-Wildenrath test center. 24 machines will get these couplers on one side, to be operated with M6 push and pull rakes, replacing the HLE 27 series locomotives currently used for this purpose. Our thanks goes out to W. Scheer.
Note the extra trapezium-shaped boxes under the coupling systems, most likely their to absorb energy when such a locomotive crashes, compensating the absence of normal buffers.
edit: MUX is not a coupling system, it is system to operate a locomotive from another cab with only one cable. Very useful for push and pull services of course. The couplings are normal GF automatic couplings. Thanks for the correction.
