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 traditionally seen on alpine coasters, since the late 2010s, a number of ride manufacturers have produced a number of conventional rollercoasters which feature single-rail track.[2][3] The vast majority of modern single-rail coasters utilise inline (single-file) seating arrangements.
