A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position. Early forms of inversions were circular in nature and date back to 1848 on the Centrifugal railway in Paris. These vertical loops produced massive g-force that was often dangerous to riders. As a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression. In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters. Elements have since evolved from simple corkscrews and vertical loops to more complex inversions such as Immelmann loops and cobra rolls. The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster with 14.
A stand-up roller coaster is a roller coaster where passengers aboard a train stand throughout the course of the ride. The first manufacturer to employ the format was TOGO, a Japanese company that converted two traditional roller coasters in 1982 to stand-up configurations. Arrow Dynamics followed suit in the United States the following year with their own conversion. The first roller coaster designed from the ground up as a stand-up coaster was King Cobra, built by TOGO, which opened at Kings Island in 1984. Intamin and Bolliger & Mabillard (B&M) have also designed stand-up models beginning in the 1990s, with the latest opening in 2023 as Pipeline: The Surf Coaster in SeaWorld Orlando.
