Have you ever heard of a railroad plough? It goes on by some other names as well, such as; Schienenwold (rail wolf) or Schwellenpflug (sleepers plough) and is a rail vehicle that features a super-strong ‘plough’ that is shaped like a hook. This device is used for destroying rail tracks in warfare, as part of the scorched earth policy to render the enemy unable to make use of the tracks.
Krupp factory manufactured Destroyers tracks back in 1942. The platform that featured the hook that went under the sleepers was hauled using two locomotives working at 7-10 km/h. The destroyer could be placed in position within 6-8 minutes and required a team of 10 persons for it operate.
