Iron Rattler at RCDB

Iron Rattler is a steel roller coaster located at Six Flags Fiesta Texas in San Antonio. The ride originally opened in 1992 as Rattler, the tallest wooden roller coaster in the world. It was converted to steel in 2013 by Rocky Mountain Construction (RMC), led by designer Alan Schilke, and reopened as Iron Rattler. RMC installed their patented I-Box track onto Rattler's existing wooden structure, increasing the drop height from 124 to 171 feet (38 to 52 m) and the maximum speed from 65 to 70 mph (105 to 113 km/h). A notable addition to its layout was a zero-g roll inversion, which was a first among hybrid coasters made of wood and steel.

The original wooden Rattler was constructed by the now-defunct and controversial Roller Coaster Corporation of America, featuring a height of 179 feet (55 m) and a drop of 166 feet (51 m). Rattler's first drop was heavily modified and reduced to 124 feet (38 m) by 1994. The transformation of the ride to Iron Rattler was well received, and it has frequently ranked in the top 50 among the world's best steel coasters in the annual Golden Ticket Awards publication from Amusement Today.
