In the course of railroad history there have been many attempts to equip locomotives with snowplow blades. Usually these aids fail with snow depths greater than 40 cm or 16". The Austrian railroader Rudolf Klima was the first to make a breakthrough with the snowplows named after him. With an adjustable plow blade and moveable side wings, these plows were quite effective in snow depths up to 1.50 meters or 59 inches. In 1929, the German State Railroad purchased its first Klima plows. The firm of Henschel in Kassel acquired the license to build them in 1931. 250 units were built in different designs, and the DB acquired about 100 units. Additional Klima snow plows were ordered right up to 1964.
