Steel Curtain (roller coaster)

The Racer is a wooden racing roller coaster located at Kennywood amusement park near Pittsburgh in West Mifflin, Pennsylvania. Built by Charlie Mach and designed by the legendary John A. Miller, the Racer opened to the public in 1927 and is one of the oldest operating roller coasters in the world. It features a Möbius loop layout, in which both of its trains travel along one continuous track. Each train returns to the opposite side of the station from which it began.

Jack Rabbit is a wooden roller coaster located at Kennywood Park near Pittsburgh in West Mifflin, Pennsylvania. Designed and built by John A. Miller and Harry C. Baker, Jack Rabbit opened in 1920, making it one of the oldest roller coasters in the world still in operation. The ride's three trains were manufactured by Edward Vettel, Sr. in 1951 and contain three cars of six seats each. The aging cars are considered a part of the ride's nostalgic experience but also lead to some young children being disallowed to enter the ride (42” is the minimum), due to the use of a small lap bar to hold in riders. A popular early feature of the ride was a tunnel which covered the turnaround section after the first drop, but this was removed in 1947 when the new cars were ordered. In 1991, the tunnel was restored, at a slightly shorter length. The Jack Rabbit was built shortly after Miller patented a new track design in 1920 (which all wooden coasters built since have used). This design involved the use of wheels both under and over the track, which allowed Miller to create the then enormous 70-foot (21 m) drop that is the attraction's largest. It is most well known for its double dip element following the lift hill. The double dip produces strong airtime that makes the rider feel that they will be thrown from the seat, and a feeling that the train leaves the track (it rises up but the upstop wheels keep it firmly on the rails). According to Rick Sebak, producer of Pittsburgh history programs for WQED, the layout and train design results in the rear seat of each train experiencing the greatest amount of airtime.In 2019, Kennywood released a video of the Jack Rabbit, likely from 1920, on their YouTube channel. The video features clips of people on the ride and clips taken from the front row seat of the Jack Rabbit. Kennywood claims their video is "the oldest coaster POV video in the world".

Kennywood is an amusement park located in West Mifflin, Pennsylvania, just southeast of Pittsburgh. The park opened on May 30, 1899, as a trolley park attraction at the end of the Mellon family's Monongahela Street Railway. It was purchased in 1906 by F. W. Henninger and Andrew McSwigan, both of whom later formed the family-owned Kennywood Entertainment Company. The company later sold Kennywood, along with four other parks, in 2007 to Parques Reunidos, an international entertainment operator based in Spain. The amusement park features various structures and rides dating back to the early 1900s. Along with Rye Playland Park, it is one of two amusement parks in the United States designated as a National Historic Landmark. Kennywood is also one of thirteen trolley parks in the United States that remain in operation.

Sky Rocket is a steel roller coaster located at Kennywood amusement park near Pittsburgh in West Mifflin, Pennsylvania.

The Sky Rocket occupies the ground near the entrance formerly occupied by Turnpike, an attraction that is expected to return to the park sometime in the future.

Thunderbolt, previously known as Pippin, is a wooden roller coaster located at Kennywood amusement park near Pittsburgh in West Mifflin, Pennsylvania. It was originally built and designed by John A.

It is partially known for being one of the few rides at Kennywood to require a partner.

Braddock Locks & Dam (previously named Monongahela Locks and Dam No. 2) is one of nine navigational structures on the Monongahela River between Pittsburgh, Pennsylvania and Fairmont, West Virginia. Built and maintained by the U.S. Army Corps of Engineers, the gated dam and the lock form an upstream pool that is for 12.6 miles (20.3 km), stretching to Elizabeth, Pennsylvania.

Phantom's Revenge is a steel roller coaster located at Kennywood amusement park in West Mifflin, Pennsylvania, United States. It originally opened as Steel Phantom in 1991, featuring the fastest speed and longest drop of any roller coaster in the world. Its second drop is longer than its first, which is a unique characteristic among roller coasters. Manufactured by Arrow Dynamics, the ride was later modified and renovated by D.H. Morgan Manufacturing for the 2001 season when it reopened as Phantom's Revenge. The drop and track length were both increased, and its four inversions were removed, enabling the removal of its unpopular over-the-shoulder restraints. The ride has consistently ranked among the top 50 steel roller coasters in the world in the annual Golden Ticket Awards publication from Amusement Today, occasionally ranking in the top 10. Additionally, it has frequently ranked in the top 5 of the National Amusement Park Historical Association's annual steel coaster survey.

The Exterminator is a steel roller coaster located at Kennywood amusement park in West Mifflin, Pennsylvania, near Pittsburgh. The ride was developed by Reverchon Industries. The ride is heavily themed around the concept of the rider as a rat attempting to escape from Kennywood exterminators. The concept is a pun of the phrase "Wild Mouse roller coaster", which describes this type of coaster, characterized by small cars (4 people/car for Exterminator) and sharp turns. Much of the theming takes place in the line for the ride, which includes such elaborate media as fake news broadcasts, and is usually the park's longest, being usually or beyond a 2 hour wait. The ride is very dark and unique, as the introduction says "unlike any ride you've rode before". The tracks are fast, rough, include a few sudden falls, and end with a fast finale that includes flashing lights, and the car seemingly spinning out of control. Like other spinning wild mouse coasters, the cars face forwards for the first half of the ride, but are free to spin during the second half.
