KUER The Roller Coaster at Lagoon is the fourth oldest roller coaster still running in the United States and the seventh oldest in the world, according to American Coaster Enthusiasts. Precursors to the roller coaster were tamer, more like a railroad with some gentle hills. John A. Miller designed Lagoon’s Roller Coaster. It featured new technology called “up-stop wheels,” patented just a couple of years before by Miller. They locked the train’s wheels under the track, making it possible to push the limits of what a roller coaster could do. “You could go steeper or taller, faster. Drops that could be dramatic,” said Geisler. Now, “you d go up and over the hill, but the coaster would stay on the track and you would kind of float over it as a passenger.”
