During World War II, the Germans designed the so called 'Schienenwölfe' (in English called a 'rail plough'), a vehicle which could destroy tracks with the use of a hook. The idea was to delay the Allied forces by destroying the railway infrastructure.
This asset is based on one that was left behind by the Germans in Rotterdam Feyenoord.
Note that these vehicles were always at the end of a train (as it would obviously be very painfull to have them do their thing in the middle), so they were not designed to have a coupler at the hook-end.
