A 600 years ago, roller coaster pioneers never would have imagined the advancements that have been made to create the roller coasters of today. The tallest and fastest roller coaster in the world is the Kingda Ka, a coaster in New Jersey that launches its passengers from zero t0 128 miles per hour in 3.5 seconds. It then heaves its riders skyward at a 90 degree angle until it reaches a height of 456 feet, over one and a half football fields above the ground before dropping another 418 feet. With that said, roller coasters are about more than just speed and height, they are about the creativity of the designers that build them, each coaster having its own unique way of producing intense thrills at a lesser risk than the average car ride. Roller coasters have evolved drastically over the years, from their primitive beginnings as Russian ice slides, to the metal monsters of today. Their combination of creativity and structural elements make them one of the purest forms of architecture.
B At first glance, a roller coaster is something like a passenger tram. It consists of a series of connected cars that move on tracks. But unlike a passenger train, a roller coaster has no engine or power source of its own. For most of the ride, the train is moved by gravity and momentum. To build up this momentum, you need to get the train to the top of the first hill or give it a powerful launch. The traditional lifting mechanism is a long length of chain running up the hill under the track. The chain is fastened in a loop, which is wound around a gear at the top of the hill and another one at the bottom of the hill. The gear at the bottom of the hill is turned by a simple motor. This turns the chain loop so that it continually moves up the hill like a long conveyer belt. The coaster cars grip onto the chain with several chain dogs, sturdy hinged hooks. When the train rolls to the bottom of the hill, the dog catches will be onto the chain links. Once the chain dog is hooked, the chain simply pulls the train to the top of the hill. At the summit, the chain dog is released and the train starts its descent down the hill.
C Roller coasters have a long, fascinating history. The direct ancestors of roller coasters were monumental ice slides — long, steep wooden slides covered in ice, some as high as 70 feet — that were popular in Russia in the 16th and 17th centuries. Riders shot down the slope in sleds made out of wood or blocks of ice, crash-landing in a sand pile. Coaster historians diverge on the exact evolution of these ice slides into actual rolling carts. The most widespread account is that a few entrepreneurial Frenchmen imported the ice slide idea to France. The warmer climate of France tended to melt the ice, so the French started building waxed slides instead, eventually adding wheels to the sleds. In 1817, the Russian Belleville became the first roller coaster where the train was attached to the track. The French continued to expand on this idea, coming up with more complex track layouts, with multiple cars and all sorts of twists and turns.
D In comparison to the world’s first roller coaster, there is perhaps an even greater debate over what was America’s first true coaster. Many will say that it is Pennsylvania’s own Maunch Chunk-Summit Hill and Switch Back Railroad. The Maunch Chunk-Summit Hill and Switch Back Railroad was originally America’s second railroad, and considered to be the greatest coaster of the time. Located at the Lehigh valley, it was originally used to transport coal from the top of Mount Pisgah to the bottom of Mount Jefferson, until Josiah White, a mining entrepreneur, had the idea of turning it into a part-time thrill ride. Because of its immediate popularity, it soon became strictly a passenger train. A steam engine would haul passengers to the top of the mountain before letting them coast back down with speeds rumored to reach 100 miles per hour! The reason that it was called a switch back railroad is that a switch back track which was located at the top-where the steam engine would let the riders coast back down. This type of track featured a dead end where the steam engine would detach its cars, allowing riders to coast down backwards. The railway went through a couple of minor track changes and name changes over the years, but it managed to last from 1829 t0 1937, over 100 years.
E The coaster craze in America was just starting to build. The creation of the Switch Back Railway, by La Marcus Thompson, gave roller coasters national attention. Originally built at New York’s Coney Island in 1884, Switch Back Railways began popping up all over the country. The popularity of these rides may puzzle the modem-day thrill seeker, due to the mild ride they gave in comparison to the modern-day roller coaster. Guests would pay a nickel to wait in line five hours just to go down a pair of side-by-side tracks with gradual hills that vehicles coasted down at a top speed around six miles per hour. Regardless of this, Switchback Railways were very popular, and sparked many people, including Thompson, to design coasters that were bigger and better.
F The 1910s and 1920s were probably the best decade that the roller coaster has ever seen. The new wave of technology, such as the upstop wheels, an arrangement that kept a coaster’s wheels to its tracks by resisted high gravitational forces, showed coasters a realm of possibilities that has never been seen before. In 1919, North America alone had about 1,500 roller coasters, a number that was rising rampantly. Then, the Great Depression gave a crushing blow to amusement parks all over America. As bad as it was, amusement parks had an optimistic look on the future in the late 1930s. But, in 1942, roller coasters could already feel the effects of World War Two, as they were forced into a shadow of neglect. Most, nearly all of America’s roller coasters were torn down. To this very day, the number of roller coaster in America is just a very tiny fraction of the amount of roller coasters in the 1920s.
