8 cars per train. Riders are arranged 2 across in a single row for a total of 16 riders per train.
History:
True heartline roller coaster.
I've seen this roller coaster also called simply "Spiral Coaster". I think that may be just the model name given to it by Intamin (the rides manufacturer). At Sky Plaza I believe it operated under the name "Sky Plaza Comet". Can anyone confirm this?
