Most modern roller coasters typically have pairs of wheels in each orientation, with 6 wheels per assembly, but this can vary by ride. The up-stop system was developed in 1919 by John A. Miller . He patented a design to make Pleasure-Railway attractions safer.
Wheels are a critical part in rollercoaster design. The purpose of wheels is to keep the train on the track and to prevent it from flying off. A majority of roller coaster wheels are made from polyurethane. There are 3 kinds of roller coaster wheels which include road wheels, side friction wheels, and up-stop wheels.
A brake run on a roller coaster is any section of track that utilizes some form of brakes to slow or stop a roller coaster train.The most common type is the friction brake, often called a fin brake, which involves a series of hydraulic-powered clamps that close and squeeze metal fins that are attached to the underside of a coaster train.
The oldest operating roller coaster is Leap-The-Dips at Lakemont Park in Pennsylvania, a side friction roller coaster built in 1902. The oldest wooden roller coaster in the United Kingdom is the Scenic Railway at Dreamland Amusement Park in Margate , Kent and features a system where the brakeman rides the car with wheels.
A roller coaster wheel assembly. The underfriction wheels are on the bottom. The three sets of wheels clamp onto the track. On a roller coaster train, the underfriction, up-lift, or up-stop wheels are a device to keep the train from jumping off the track under intense movement. [1] The design was patented in 1919 by John A. Miller. [2] [3]
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many ...

The physics of roller coasters comprises the mechanics that affect the design and operation of roller coasters, a machine that uses gravity and inertia to send a train of cars along a winding track. Gravity, inertia, g-forces , and centripetal acceleration give riders constantly changing forces which create certain sensations as the coaster ...
