Roller Coasters used to come in 2 flavors, Wood and Steel. Both use gravity to pull the ride throughout the layout and for many years after they were introduced were all the same. Up the hill, slowly being pulled by a heavy, inefficient chain where it was released to travel the length of it layout. Top Thrill Dragster, at Cedar Point uses gravity, but only for the latter half of the ride. The first half of this 30 second ride uses kinetic energy to get the trains down 480 feet of track and up a ridiculous 420’ hill.
