THE tallest and fastest single rail rollercoaster is to open next year at Six Flags.
Called the Jersey Devil Coaster, the new ride will open at Great Adventure in New Jersey in 2020 - and is one of the few single track coasters in the world.
The 13-storey ride will reach speeds up to 58mph.
With more than 3,000ft (914m) of track, riders will travel with their legs straddling the monorail in single file in a carriage designed to look like the devil.
The ride will even feature a terrifying 87-degree drop, before being propelled through a number of inversions and dives.
The designers behind the roller coaster said it was inspired by "New Jersey mythology".
The story of the Jersey Devil dates back to the 1700s of an ugly winged creature which was the 13th child of a woman in Pine Barrens, who cursed it.
Sightings since of the creature have been reported, with the , Napoleon's brother, who said he saw it on his estate in 1820.
Single rail rollercoasters are less common then double railed rollercoasters, due the lack of variation when it comes to models such as floor-less or inverted.
However, single rollercoasters can be much smoother due to the one track as well as offer single seat carriages as opposed to two or three.
There are only two other single rail coasters in the world - RailBlazer at California's Great America, and Wonder Woman: Golden Lasso Coaster at Six Flags Fiesta Texas.
