Other Information

Incredibly difficult coaster to design. To avoid financial difficulties and time limits, only attempt to design one in the Rollercoaster Designer or Sandbox Mode.

Special Uses

This ride can be used to create an Intamin ZacSpin-esque coaster using 8 cars per Trainer. Simply use the "toggle chain" command in the trainer on a vertical track section to create a vertical lift, then use a combination of quarter loops and steep track sections to create the narrow (1 by X) layout.

In Real Life

This type of coaster is called the 4th Dimension roller coaster, originally built by Arrow Dynamics. The first of this type is X2 (formerly X) at Six Flags Magic Mountain. Newer versions of these are built by S&S, such as Dinoconda in Dinosaurs Park, China.
