The story of Colossus

For its 1978 season, Magic Mountain sought the older music of timber, a rumble and sway that the steel coasters of the day could not quite supply. International Amusement Devices began the design work in January 1977, and construction followed that August, giving Valencia a great paired course of wood. en.wikipedia.org

When Colossus opened to visitors on June 29, 1978, it was presented as an engineering achievement of unusual scale. At 38.1 metres tall and 100 km/h, it stood among the grandest wooden rides of its day, and its two tracks allowed the afternoon crowds to move in handsome procession. en.wikipedia.org

The ride was altered as the years passed. In 1979 it closed for about ten months while several hills were reprofiled, and later train and braking changes followed. Colossus remained a park landmark through these revisions, a broad timber presence for generations of Southern California visitors. en.wikipedia.org

Six Flags marked August 16, 2014, as the final operating day for Colossus, closing its 36-year reign at the park. Later that month the company announced Twisted Colossus, a 2015 conversion using Iron Horse steel track while retaining much of the old wooden structure. s204.q4cdn.com· prnewswire.com
