This Whirlwind model was shown at Interschau 82 (trade fair in Düsseldorf, Germany) along with a Paratower. Both rides were operating in January 1982.
Speed Snake originally had a train built by Arrow. Starting in 2010, Speed Snake uses the Vekoma built train that formerly operated on the Boomerang at Wiener Prater in Vienna, Austria. As of June 15th 2017, Speed Snake got a new train by Sunkid Heege Gmbh and was renamed 'SpeedSnake FREE' to refer to the new train just having lap bars.
