A railroad plough (German: Schienenwolf ("rail wolf") or German: Schwellenpflug ("sleeper plough") or (German: Schwellenreißer ("sleeper ripper")) is a rail vehicle which supports an immensely strong, hook-shaped plough. It is used for destruction of sleepers in warfare, as part of a scorched-earth policy, so that the track becomes unusable for the enemy.
In use, the plough is lowered to rip up the middle of the track as it is hauled along by a locomotive. This action breaks the wooden ties which forces the steel rails out of alignment, making the line impassable by later rail vehicles. Bridges and signalling equipment also suffer serious damage.
A similar device, which ripped the rail off the ties, had been used by railway troops of the Imperial Russian Army in World War I, during their retreat from Galicia and Poland. Railroad ploughs were in use by the Czechoslovak Army during the German occupation in 1938, and by German Wehrmacht armed forces retreating northward through Italy and westward from the Eastern Front in World War II.
Today, the targeted destruction of civil infrastructure is considered a war crime. The German author Arno Schmidt (1914–1979) in his post-war novel Leviathan uses the image of a railroad plough as a symbol of evil.
