XLR-8 (pronounced "accelerate") was a steel suspended roller coaster. It was designed by Arrow Dynamics (at the time called 'Arrow-Huss') and located at Six Flags AstroWorld from when it was constructed in 1984 until the park closed in 2005. It was the successor to the troubled Bat at Kings Island, which had closed due to several problems.

Car reversal[edit]

For AstroWorld's Fright Fest 2002 event, the last four cars on XLR-8's trains were reversed, which had never been done before on any other suspended roller coaster. The change was successful, and the trains remained like that until the park's closure in 2005.[citation needed]


On September 12, 2005, it was announced that AstroWorld would close permanently at the end of the 2005 season and would be demolished shortly afterwards. XLR-8 closed along with the rest of the park on October 30, 2005. On February 3, 2006 it was sold for $50,000 and scrapped. The train cars were sent to Six Flags Magic Mountain, where they are now used on Ninja.[citation needed]
