Wooden Roller Coaster - Wooden Versus Steel

Wooden Versus Steel

Wooden roller coasters provide a very different ride and experience from steel roller coasters. While they are traditionally less capable than a steel coaster when it comes to inversions and elements, wooden coasters instead rely on an often rougher and more "wild" ride, as well as a more psychological approach to inducing fear. Their structures and track, which usually move anywhere from a few inches to a few feet with a passing train, give a sense of unreliability and the "threat" of collapse or disregard for safety. Of course, this assumption is purely mental, and wooden roller coaster supports and track systems are designed to sway with the force. If the track and structure are too rigid, they will break under the strain of the passing train. The swaying of the track reduces the force applied per second (see impulse), like a shock absorber.

Like steel roller coasters, wooden roller coasters usually use the same three-wheel design, pioneered by John Miller. Each set of wheels includes a running wheel (on top of the track), a side friction (or "guide") wheel (to guide motion in the lateral plane and reduce excessive side-to-side movement known as "hunting") and an upstop wheel (beneath the track to prevent cars from flying off the track). Some wooden coasters, such as Leap-The-Dips, do not have upstop wheels and are known as side friction roller coasters. As a result, the turns and drops are more gentle than on modern wooden roller coasters. Scenic Railway roller coasters also lack upstop wheels but rely on a brakeman to control the speed so that upstop wheels are not necessary. A handful of wooden coasters use flanged wheels, similar to a rail car, eliminating the need for side friction wheels.

The debate rages as to which type of coaster is better: wood or steel. This is unlikely to ever be settled, however, because each category distinguishes itself from the other in a number of ways, in addition to also providing a substantially different and unique ride.
