Roller Coaster Ride For Sale

A roller coaster is an amusement ride developed for amusement parks and modern theme parks rides. LaMarcus Adna Thompson obtained a patent regarding roller coasters on January 20, 1885, which were made out of wood, but this patent is considerably later than the "Russian mountains" described below. In essence a specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more inversions (such as vertical loops) that briefly turn the rider upside down. The track does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably wild mouse roller coasters, run with single cars.

Steel roller coasters
In 1959 Disneyland introduced a new design breakthrough with Matterhorn Bobsleds. This was the first roller coaster to use a tubular steel track. Unlike wooden coaster rails, which are generally formed using steel strips mounted on laminated wood, tubular steel can be easily bent in any direction, which allows designers to incorporate loops, corkscrews, and many other maneuvers into their designs. Most modern roller coasters are made of steel, although wooden coasters are still being built.
