A
wooden roller coaster is most often classified as a
roller coaster with running rails made of flattened steel strips mounted on laminated
wooden track. Occasionally, the support structure may be made out of a
steel lattice or
truss, but the ride remains classified as a wooden roller coaster due to the track design. Because of the limits of
wood, wooden roller coasters in general do not have
inversions (when the coaster goes upside down), steep drops, or extremely banked turns (
overbanked turns). However, there are exceptions; the defunct
Son of Beast at
Kings Island had a drop and originally had a
loop until the end of the 2006 season, although the loop had metal supports. Other special cases are
Hades 360 at
Mount Olympus Water and Theme Park in
Wisconsin Dells, Wisconsin, featuring a double-track tunnel, a Corkscrew, and a 90-degree banked turn,
The Voyage at
Holiday World (an example of a wooden roller coaster with a steel structure for supports) featuring three separate 90-degree banked turns,
Ravine Flyer II at
Waldameer Park which has a 90-degree banked turn,
T Express at
Everland in
South Korea with a 77-degree drop, and
Outlaw Run at
Silver Dollar City which has 3 inversions and 120-degree
overbanked turn.
