Centrifugal Railway was the name of a number of early looping roller coasters that were built in Western Europe in the middle of the 19th century. These rides were very similar in their basic design to many modern-day shuttle roller coasters (i.e., they did not make a complete circuit), but with only one lift hill and no launch. A single roller coaster car would ascend to the peak on the coaster before descending rapidly down the same hill and then passing through the central loop with enough speed to remain on the track at the top of the loop. The size of these centrifugal railways differed; some were purported to have vertical loops of a mere 2 metres (6.6 ft), while others were estimated to be 12 metres (39 ft) (although, as described below, early coaster designers were prone to cases of gross exaggeration).

Centrifugal railway in the context of Centrifugal force
In Newtonian mechanics, a centrifugal force is a kind of fictitious force (or inertial force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed perpendicularly from the axis of rotation of the frame. The magnitude of the centrifugal force F on an object of mass m at the perpendicular distance ρ from the axis of a rotating frame of reference with angular velocity ω is .
The concept of centrifugal force simplifies the analysis of rotating devices by adopting a co-rotating frame of reference, such as in centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves. The same centrifugal effect observed on rotating devices can be analyzed in an inertial reference frame as a consequence of inertia and the physical forces without invoking a centrifugal force.
