snow for the benefit of photographers and railway enthusiasts. Rotaries of newer construction are either diesel- or electric-powered. Many steam plows were converted to electricity. Some electric plows can take their power from a locomotive, while others are semi-permanently coupled to power units, generally old locomotives with their traction motors removed; these are colloquially called "snails." (This is derived from the fact that engineless but motored units that take their power from another locomotive are "slugs"; thus the opposite, with engine but no motors, is a "snail.") Hall of Fame induction In 2001, the rotary snowplow was inducted into the North America Railway Hall of Fame. The hall of fame recognizes and establishes an enduring tribute to the people and things that have made significant contribution relating to the railway industry in North America. The rotary snowplow was inducted in the "Technical Innovations" category with "National" significance.
