An Impulse roller coaster is a form of a launched inverted roller coaster manufactured by Intamin. The first Impulse roller coaster appeared in Japan, and the ride type has since evolved to include four specific layouts, three of these varieties being built in the United States. It uses LIMs to launch a train out of the station and up a vertical spiral. The train then falls backward, is powered again through the station, and heads up a back tower. The train then falls forward, and continues in this fashion for a total of 2½ cycles per ride. On the final forward launch, with a slightly reduced speed, the train is sent up the front tower, and brakes then deploy on the launch track. The train then slows down and heads back into the station.
