4th Dimension roller coaster

A 4th Dimension roller coaster is a type of roller coaster in which the cars have the ability to rotate on an axis perpendicular to that of the track. This rotation is either controlled, via extra rails on the track, or uncontrolled, allowing for a ride experience which varies depending on the weight distribution of the car.

History[edit]

Arrow Dynamics[edit]

The first 4th Dimension coaster to be built was X at Six Flags Magic Mountain. It was designed and built by the manufacturer, Arrow Dynamics and was the last ride to be made by them.

S&S[edit]

The 4th Dimension design was bought along with the rest of Arrow Dynamics by S&S Worldwide. The company proceeded to sell two more 4th Dimension coasters; one in Japan, Eejanaika, and the other in China, Dinoconda. Both of these projects were manufactured by regional companies, subcontracted by S&S.

After the 50% acquisition of S&S Worldwide by Sansei Yusoki, Co., Ltd, a new, smaller 4th Dimension roller coaster was sold to Six Flags Fiesta Texas under the name S&S Sansei. Batman The Ride opened in 2015 and features free-spinning seats. A clone of this ride opened at Six Flags Great Adventure the following year.

Design[edit]

The seats on the train are located at either side of the track. These seats are rotated to different angles at different points in the ride to add excitement.

Mechanics[edit]

The rotation of the cars is achieved by having four rails on the track: two of these are running rails while the other two are for spin control. The two rails that control the spin of the seats move up and down relative to the track and spin the seats using a rack and pinion gear mechanism.

Similar Rides[edit]

The trains on a winged roller coaster are similar to a 4th Dimension train. Both ride types seat riders at either side of the track, but a winged roller coaster does not rotate riders.
