Fun Fact
Magnetic brakes: Magnetic brakes on modern roller coasters require absolutely no electricity to function, making them fail-safe even during power outages.
Glossary
upstop wheel (noun)
A roller coaster wheel that grips the underside of the track to prevent the car from lifting off. In 1919, John Miller patented this device, allowing trains to safely navigate steeper drops at higher speeds.
