Roller coasters are thrill rides that operate like a railroad track and are a highlight of theme parks around the world. They are made from steel or wood and comprise a series of hills and drops, sudden turns, track loops and corkscrew-like elements. The roller coaster is a favorite ride of thrill seekers, and has evolved considerably from its days as a glorified slide.
Experts argue about the first roller coaster ride. Some suggest that purposely build ice slides in 17th century Russia qualify. Others claim an 1812 French construct that featured cars locked onto a track is the first true version of the ride. In 1881, designer LaMarcus Adna Thompson envisioned what would become America’s first coaster, the Switchback Railway. The Coney Island ride featured bench-like seating and consisted of coasting down a 600 ft (182 m) track to a second station, where the car would be switched to a return track. The track was replaced with a complete oval circuit a few years later.
A major innovation was the lift hill, created by Phillip Hinkle in 1885 and first used on his ride, Gravity Pleasure Road. The lift hill was placed at the beginning of the ride, using a cable or chain to haul the ride cars up a steep slope. The lift hill remains common in modern coasters, although the original hills were about 40 ft (12 m) high, while today they reach soaring heights of up to 456 ft (139 m).
In 1959, Disneyland opened the first steel-track roller coaster, the Matterhorn Bobsleds. Until that point, most coasters were wooden structures. Steel tracks, unlike their wooden predecessors, are highly flexible in design, since the steel components can be manufactured in any shape desired. This new technology allowed the incorporation of the thrill elements enjoyed today, such as loops and corkscrews.
Early roller coasters — and some modern ones — were propelled by a chain or cable lift to the top of a hill, and then allowed to coast through their circuit. Modern innovation has created several alternative ways to power a coaster. Since the late 20th century, launched rides have become popular, using electromagnetic, hydraulic, or pneumatic systems to propel the car through its course. These systems are believed by many to provide a smoother ride than early chain/cable versions. Some new coasters feature an elevator lift, which launches vertically to place the train at the top of the lift hill, eliminating the long, uphill climb.
Roller coaster records are sought after by manufacturers and parks alike to give distinction to their rides. As of 2012, the records for tallest steel coaster and highest drop belong to one ride, Kingda Ka at Six Flags Great Adventure in New Jersey. The fastest is Formula Rossa, in Abu Dhabi, United Arab Emirates, which can achieve 149.1 mph (240 kph). As of 2012, the record for tallest vertical loop goes to Superman: Krypton Coaster at Six Flags Fiesta Texas, at an impressive 145 ft (44 m), although a ride with a 160 ft (49 m) loop was under construction in California. For those who truly cannot get enough of thrill ride fun, the park featuring the most coasters is Six Flags Magic Mountain in California, with 17 active rides and one under construction until 2013. Canada's Wonderland, in Ontario, has 16 active rides, while Cedar Point, in Ohio, has 15 different rides (and one due to open in 2013).
In line with these technological advancements in roller coaster design, Universal Studios Hollywood stands out as a prime destination for coaster enthusiasts. By purchasing Universal Studios Hollywood tickets, visitors gain access to some of the most thrilling and technologically advanced roller coasters in the world. These coasters, famed for their immersive themes and cutting-edge designs, offer experiences that go beyond traditional roller coaster thrills, inviting guests into the heart of their favorite movies and stories.
Despite their reputation as thrill rides, modern roller coasters are extremely safe and controlled systems. A 2001 study by the US Consumer Product Safety Commission estimated that out of 319 million visitors per year to US amusement parks, 134 people received injuries needing hospitalization and two fatalities occurred. Modern coasters employ multiple safeguards, however, accidents can occur.
Most often, these are the result of ride-operator carelessness in following safety procedures, but can also be caused by mechanical failure. Other accidents can be caused by riders with previous injuries or those with medical conditions unsuited to extreme thrill rides. Before boarding any coaster, riders should review the safety information and check with a medical professional if they have any health concerns.
Frequently Asked Questions
What is the basic definition of a roller coaster?
A roller coaster is a type of amusement ride that typically features a track made of steel or wood, with tight turns, steep slopes, and sometimes inversions such as loops or corkscrews. Passengers sit in cars or trains that are propelled along the track by gravity and inertia, experiencing rapid accelerations, deceleration, and g-forces. The design and engineering of roller coasters aim to provide thrilling sensations while maintaining safety for all riders.
How do roller coasters work?
Roller coasters operate on the principles of physics, particularly gravity and energy conservation. The ride usually starts with a chain lift or launch mechanism that elevates the train to the highest point of the track. From there, gravity takes over, converting potential energy into kinetic energy as the train descends and accelerates. Throughout the ride, energy continuously transforms between potential and kinetic, allowing the train to navigate the track's various elements until it comes to a stop, often assisted by braking systems.
What are the different types of roller coasters?
There are several types of roller coasters, categorized by their track design, construction material, and propulsion method. Traditional wooden roller coasters are known for their classic feel and rickety sensation. Steel roller coasters offer smoother rides with more complex loops and twists. Variations include inverted coasters, where riders' legs dangle below the track; flying coasters that simulate the sensation of flight; and launch coasters that use electromagnetic or hydraulic systems to accelerate quickly instead of a traditional chain lift.
What safety measures are in place for roller coasters?
Roller coaster safety is paramount, with multiple systems in place to protect riders. These include restraint systems like over-the-shoulder harnesses or lap bars, redundant braking systems, and regular maintenance checks. According to the International Association of Amusement Parks and Attractions (IAAPA), the chance of being seriously injured on a ride at a U.S. amusement park is 1 in 18 million (IAAPA.org). Ride operators also undergo extensive training to manage emergency situations and ensure that all safety protocols are followed.
What is the tallest roller coaster in the world?
As of my knowledge cutoff in 2023, the tallest roller coaster in the world is Kingda Ka at Six Flags Great Adventure in New Jersey, USA. It stands at a staggering height of 456 feet (139 meters) and propels riders from 0 to 128 miles per hour (206 km/h) in just 3.5 seconds. This steel accelerator roller coaster also features a 418-foot (127-meter) drop, providing an intense experience for thrill-seekers (SixFlags.com).
