The parks first indoor roller coaster. The Exterminator is a combination of many different rides. First it provides the thrills of a roller coaster! Second it spins you around and around like one of those Tea Cup rides! Third it provides the thrills of a dark ride. Some of the areas inside include underground sewer systems, a slime room, an electrical room, a boiler room, a destroyed section of track, a tunnel illusion, a giant rat, plus numerous special effects. Put all these images together and you have a coaster car spinning in circles, as it travels around the track in this dark themed building.

The Jack Rabbit roller coaster marked a new era in Kennywood coaster history. This was the first coaster at Kennywood to use a system of upstops, or wheels under the track. This prevented the coaster cars from ever leaving the track, thus hills could be made steeper, which enabled for faster speeds. This coaster was designed by John Miller.

In 1927 John Miller built a third coaster for Kennywood, this was the last coaster he ever designed. This time it was a single track racing coaster called the Racer, it features two cars that race on a track that is actually one long loop, so if you start on the right you will end up on the left, and vice versa.
