Railway companies used similar tracks to provide amusement on days when ridership was low. Using this idea as a basis, LaMarcus Adna Thompson began work on a gravity Switchback Railway that opened at Coney Island in Brooklyn, New York, in 1884. Passengers climbed to the top of a platform and rode a bench-like car down the track up to the top of another tower where the vehicle was switched to a return track and the passengers took the return trip. This track design was soon replaced with an oval complete circuit. In 1885, Phillip Hinkle introduced the first full-circuit coaster with a lift hill, the "Gravity Pleasure Road", which became the most popular attraction at Coney Island. Not to be outdone, in 1886 Thompson patented his design of roller coaster that included dark tunnels with painted scenery. "Scenic Railways" were soon found in amusement parks across the county. By 1919, the first underfriction roller coaster had been developed by John Miller. Soon, roller coasters spread to amusement parks all around the world. Perhaps the best known historical roller coaster, "Cyclone", was opened at Coney Island in 1927. The Great Depression marked the end of the golden age of roller coasters, and theme parks, in general, went into decline. This lasted until 1972 when the instant success of "The Racer" at Kings Island began a roller coaster renaissance which has continued to this day. In 1959, Disneyland introduced a design breakthrough with "Matterhorn Bobsleds", the first roller coaster to use a tubular steel track. Unlike wooden coaster rails, tubular steel can be bent in any direction, allowing designers to incorporate loops, corkscrews, and many other maneuvers into their designs. Most modern roller coasters are made of steel, although wooden coasters and hybrids are still being built. There are several explanations of the name "roller coaster". It is said to have originated from an early American design where slides or ramps were fitted with rollers over which a sled would coast. This design was abandoned in favor of fitting the wheels to the sled or other vehicles, but the name endured. Another explanation is that it originated from a ride located in a roller skating rink in Haverhill, Massachusetts in 1887. A toboggan-like sled was raised to the top of a track which consisted of hundreds of rollers. This "Roller Toboggan" then took off down gently rolling hills to the floor. The inventors of this ride, Stephen E. Jackman and Byron B. Floyd, claim that they were the first to use the term "roller coaster".
