The major roller coasters in the United States

They are almost a perversion of the pleasure-pain principle. We are drawn to them even as they incite fear, get our hearts racing, turn our knuckles white, and toss us around mercilessly. Then we get off and jump right back in line.

 Every history has a starting point and most roller coaster historians agree that the roller coaster's origins were the [|Russian Ice Slides]. LaMarcus Adna Thompson patented the first coasters on January 20, 1885. Other historians believe that the first roller coaster was built by the French. The //Les Montagnes Russes à Belleville// (//The Russian Mountains of Belleville//) constructed in Paris in 1812 and the //Promenades Aeriennes// both featured wheeled cars securely locked to the track, guide rails to keep them on course, and higher speeds.

Safety ** Many safety systems are implemented in roller coasters. One of these is the [|block system]. Most large roller coasters have the ability to run two or more trains at once, and the block system prevents these trains from colliding. . At the end of each block, there is a section of track where a train can be stopped if necessary (either by preventing dispatch from the station, closing brakes, or stopping a lift). Sensors at the end of each block detect when a train passes so that the computer running the ride is aware of which blocks are occupied. When the computer detects a train about to travel into an already occupied block, it uses whatever method is available to keep it from entering.
