The Iron Rattler roller coaster at Six Flags Fiesta Texas is currently closed while an investigation is carried out into the death of a woman on the similar Texas Giant coaster at Six Flags Over Texas.
Both Iron Rattler and Texas Giant use a hybrid wood-steel construction, featuring an "Iron Horse" track. Both rides were updated during the last two years to enable a smoother ride experience, after complaints that the previous versions were overly rough.
The Texas Giant is also closed after the fatal accident on July 19, which saw a woman fall from the ride's train. The exact circumstances of the incident are yet to be confirmed by Six Flags.
The Iron Rattler's first drop was updated for 2013 to stand at 171-feet-tall, with riders plummeting down it at an 81-degree angle. At the base of the drop, they hit a top speed of 70 miles per hour before racing through a series of four overbanked turns and a barrel roll inversion.
The original Rattler was the tallest and fastest wooden roller coaster in the world when it opened in 1992, standing at some 179-feet-tall. Riders hit a top speed of 73 miles per hour at the base of its first drop, which was subsequently shortened by 42 feet. This reduced the speed to 65 miles per hour, with Six Flags Fiesta Texas aiming to address complaints that the ride was too intense.
