Single-rail roller coaster

A single–rail 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.^[1] While normally seen on alpine coasters, in recent years, manufacturers such as Rocky Mountain Construction, Intamin and Skyline Attractions have produced a number of more conventional thrill-focused rollercoasters with single-rail track.^[2][3] The vast majority of modern single-rail coasters utilise inline (single-file) seating arrangements.
