Early Arrow Dynamics steel roller coasters oriented the side frictions wheels on the inside of the rails. Side friction wheels keep the train centered in the track, avoiding derailment. The final set of wheels in the assembly are known as running wheels, road wheels, or tractor 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]
Roller coaster wheels. Roller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running wheels); these lock the train to the tracks and prevent it from jumping the track. The side wheels can be mounted on the ...
June 24, 1941. (1941-06-24) (aged 68–69) Houston, Texas, U.S. Occupation. Roller coaster engineer. John A. Miller, born August John Mueller (1872 – June 24, 1941), was an American roller coaster designer and builder, inventor, and businessman. Miller patented over 100 key roller coaster components, [1] and is widely considered the "father ...
A side friction roller coaster is an early roller coaster design invented by Edward Joy Morris. The design introduced side-friction wheels to help prevent trains from derailing during curved portions of the track. In addition to weight-bearing wheels traditionally located on the underside of each train car, friction wheels were added to both ...
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 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 ...
