Diamond Back shuttle loop roller coaster at Frontier City

This is the Diamond Back roller coaster at Frontier City in Oklahoma City, OK. It is a Shuttle Loop built in 1978 by Arrow and
was one of two shuttle loop coasters at Six Flags Great Adventure called Lightning Loops. It opened at Frontier City in 1993.

Arrow constructed eight shuttle loops, but only three are in operation today. Besides Diamond Back, Revolution (previously known as Irn-Bru Revolution) has been running at Blackpool Pleasure Beach in England since 1979, and Sidewinder has been looping at Elitch Gardens since 1995. That ride was also Sidewinder at Denver’s first Elitch Gardens from 1990 to 1994. Before that, it was the Roaring Tornado at Magic Springs & Crystal Falls in Hot Springs, Arkansas from 1980 to 1989.
