MonteZOOMa: The Forbidden Fortress
MonteZOOMa: The Forbidden Fortress, previously known as Montezooma’s Revenge, is a shuttle roller coaster located at Knott's Berry Farm in Buena Park, California, United States. Designed by Werner Stengel and built by Schwarzkopf Industries GmbH, the ride opened to the public on May 21, 1978. It is one of eight flywheel-launched units around the world and the oldest looping shuttle coaster still operating in its original location. Montezooma’s Revenge closed in early 2022 for a major refurbishment. Originally scheduled to reopen in 2023, MonteZOOMa: The Forbidden Fortress has had its reopening postponed indefinitely due to construction delays.
History
Montezooma's Revenge was named after the bluegrass group, Montezuma's Revenge, a musical act that performed regularly in the wagon camp at Knott's Berry Farm. Based on the launch mechanism for aircraft carriers, the flywheel-launched shuttle loop is a successor of the drop-tower launch shuttle, and predates modern LIM and hydraulic launch systems by over 15 years. The drop tower models had a large silo with a weight inside connected to a similar launch system. The weight would drop, thus pulling the cable and bob, launching the train. Drawbacks included no adjustments for inclement weather. Also, the drop-tower launch was nowhere as intense as the flywheel launch, taking almost two seconds longer to reach the same speed.The nearby Jaguar! roller coaster, which opened in 1995, passes directly through the center of Montezooma's loop. In 2002, Montezooma's Revenge was repainted in a teal and yellow color scheme. In 2008, Knott's opened Pony Express, a small "out and back" steel roller coaster with a flywheel launch system much like Montezooma's Revenge.
In 2017, Montezooma's Revenge was painted with orange track and dark green supports.
Refurbishment and new name
Montezooma’s Revenge closed with little notice in 2022 for a major refurbishment. The abrupt closure prompted the park to accommodate fans and reopen the ride the following day, giving enthusiasts another chance to ride before the extended closure. At the time, it was expected that the refurbished ride would reopen in 2023 along with a revamped Mexican-themed Fiesta Village area, but the date has been postponed multiple times.Some of the expected changes include a modernized launch and braking design, as well as an updated treasure-hunting theme and backstory. The refurbished coaster will be renamed "MonteZOOMa: The Forbidden Fortress".
During construction, the ride's loop was replaced with an identical design painted red – the original loop was donated to the National Roller Coaster Museum and Archives along with the original signage and trains., the ride's planned reopening date is still unknown.
Ride description
The ride uses a flywheel mechanism to accelerate the train to in 4.5 seconds. The train goes through a vertical loop, then ascends a spike and reverses direction. It passes through the station in reverse and ascends another spike behind the station before returning back. The flywheel, located outside the station and adjacent to the loop, is attached to a clutch and cable system, which in turn connects to a small four-wheeled catch car known as a "bob". On the front of the bob is a launch pin that seats in a socket in the back of the train. Once the bob is seated, the operators receive the ready light.At launch, the clutch system engages the cable to the spinning flywheel, pulling the bob and train rapidly forwards. During the launch sequence, enough kinetic energy is removed from the flywheel to reduce its speed from approximately 1044 rpm to 872 rpm. The train negotiates a diameter vertical loop before ascending the front spike, then descends backwards, going through the loop a second time, running at full speed backwards through the station, and ascending the rear spike. It is at this point where the best "airtime" on the ride is experienced. The train then returns to its starting position after being slowed by 66 sets of brakes, 33 in the station and 33 to the rear of the station.
Unlike traditional looping coasters that use over-the-shoulder restraints, MonteZOOMa originally only relied on a conventional lap bar restraint to secure riders. Following Cedar Fair's 1997 acquisition of Knott's Berry Farm, fabric seat belts were added as a secondary restraint to complement the existing lap bar restraints.
