Tri-Star
If you've ever ridden the Enterprise and wished for three times the thrill, then for a short while the Tri-Star would have been right up your street. This more overt thrill ride had gondolas and a lifting arm not too dissimilar to Enterprise, but those gondolas sat on one of three spinning wheels that rotated on one of three arms.
The Tri-Star was installed by Tussauds on Talbot Street in 1991 to replace the 4 Man Bob. It originally operated in Coaster Corner, but when this area was decommissioned in 1992 it was moved into Festival Park. For one season it span alongside its cousin, the Enterprise, but its time at Alton Towers was fleeting and it was removed at the end of the 1992 season.
But the story didn't end there... As with many rides removed by Tussauds in the early 90s, the Tri-Star found its way to Pleasure Island in Cleethorpes. It has since gone on to operate in Flamingo Land and more recently Pleasurewood Hills, where it opened as Thunderstruck and later Tide Traveler. Unfortunately, it looks like the ride was decommissioned in 2017 and has therefore come to the end of its working life after 40 years of operation.
