A singleâÂÂrail roller coaster is a roller coaster that rides on only one rail, as opposed to the far more conventional two-rail setup of most roller coasters. The use of a single-rail design can often reduce costs in the manufacturing and construction process, and allow for a more compact ride footprint. While traditionally seen on alpine coasters, since the late 2010s, a number of ride manufactuerers have produced a number of conventional rollercoasters which feature single-rail track. The vast majority of modern single-rail coasters utilise inline (single-file) seating arrangements.
Rocky Mountain Construction was the first manufacturer to produce modern single-rail coasters, opening their first in 2018. As of 2025, the company's only single-rail model on offer is the Raptor, an -seated high thrill model.
Intamin's primary single-rail model on offer is the Hot Racer, a launched model featuring seating. As of 2025, three have been built.
Skyline Attractions offers a range of different single-rail models. Family and kiddie models such as the P'sghetti Bowl are traditional coasters, while the Skywarp thrill model utilises two trains that are uniquely mechanically linked. As of 2025, all coasters designed by Skyline are permanently closed.
