Impulse (roller coaster)

Impulse is a steel roller coaster located at Knoebels Amusement Resort in Elysburg, Pennsylvania. It is manufactured by Zierer and is the first major steel coaster to open at Knoebels since Whirlwind closed in 2004. Impulse was the park's most expensive addition when it was completed in 2015.

History
The park had been looking for a new roller coaster after Whirlwind was closed and shipped to Parque de Diversiones in Costa Rica in 2004. The park hired German manufacturer Zierer Rides to design the new ride. The actual design process did not start until 2009. Construction began in July 2013, and the coaster was assembled at the park in late February 2015. The project was complete by April 2015.

Impulse replaced the Bumper Boats ride, which was purchased from Rocky Glen Park in Moosic, Pennsylvania in the 1980s.

Ride experience
Riders are restrained by a lap bar which goes across the legs and the waist. The ride features small 8 passenger trains, resulting in a low capacity.

The ride begins by rounding a bend and then climbing the 98 ft (30m) lift hill. The train then proceeds to drop straight down into the first inversion, a cobra roll. The train then goes into a vertical loop, followed by a series of twists and turns around the vertical lift hill until it enters the final inversion, a zero g roll. The train then goes into a short but intense helix before entering the brake run and returning to the station. The complete ride is one minute and 20 seconds.

Riders can also purchase a photograph of themselves on the roller coaster after the ride is through.
