Steel roller coaster
From Wikipedia, the free encyclopedia
A steel roller coaster is a roller coaster that is defined by having a track made of steel. The vast majority of steel coasters have a steel support structure, but several have a wooden support structure: Cedar Creek Mine Ride and Gemini at Cedar Point and Excalibur at Valleyfair!. These coasters are still considered steel coasters because their tracks are made of steel. Steel coasters have earned immense popularity in the past 50 years throughout the world. Incorporating tubular steel track and polyurethane-coated wheels, the thrill rides can provide a taller, smoother, and faster ride with more inversions than a traditional wooden roller coaster.
Arrow Dynamics first introduced the steel roller coaster to the thrill industry with their creations of the Matterhorn (Disneyland) and the Runaway Mine Train (Six Flags Over Texas).
As of 2006, the oldest operating steel roller coaster in North America is the Little Dipper at Memphis Kiddie Park in Brooklyn, Ohio and has been operating since April 1952.
