Iron Rattler

Iron Rattler is a steel roller coaster located at Six Flags Fiesta Texas in San Antonio, Texas. The ride opened in 2013 as a conversion of the Rattler, a wooden roller coaster that had opened in 1992. Iron Rattler is the first hybrid wood and steel roller coaster to feature an inversion, namely a zero-g-roll.
Iron Rattler was designed by Alan Schilke and built by Rocky Mountain Construction . The wooden Rattler had been constructed by Roller Coaster Corporation of America. At the time of its opening, the Rattler was the tallest and fastest wooden coaster in the world, with a height of 179 feet , a first drop of 166 feet and a top speed of 73 mph . RMC modified the wooden Rattler by placing new steel track on top of the existing wooden support structure. The distance between the lowest and highest points of the first drop was increased from 124 to 171 feet and the drop was made steeper by changing the angle to 81 degrees. The resulting modifications increased the speed of the trains from 65 to 70 miles per hour .
