Hi guys. In this thread, I'm discussing what coaster types never really took off. When I thought of this, four ride types sprung to mind. These are: Intamin Prefabricated Wooden Rollercoaster - Since the ride type's premiere in 2001, only four of these have been built, with the most recent opening 10 years ago in 2008. I'm not even sure whether Intamin still sells these. Vekoma Invertigo - Since the ride type's premiere in 1997, only four have been built, with the most recent one to open, excluding relocations, being 19 years ago in 1999. As the newest Invertigo is turning 20 in 2019, I don't see any more of these being sold. If Vekoma still sells them, that is. Vekoma Giant Inverted Boomerang - Since the ride type's premiere in 2001, six have been built, with the most recent one to open, excluding relocations, being 4 years ago in 2014. From what I've read online, these are generally quite good rides, but they have generally been a reliability nightmare for parks that have built them, so I don't know if we're going to see any more get built. Now, the fourth one is a bit of a controversial one, but I'm going to suggest: Drop Track Coasters in general - Now, it may be a tad unfair for me to judge this type as it is still relatively new, but hear me out. Since the ride type's premiere in 2010, five have been built excluding the Chinese contraption manufactured by an unknown company, with the most recent of these to open, again excluding the Chinese thing, being 4 years ago in 2014. While there is still time for more of these to be built, I don't think many have really been sold in the 8 years the ride type has existed for, and I don't see any sudden surge in drop track coasters coming any time soon. So, these are the coaster types that I feel never really took off. Do you guys disagree with me? P.S. Sorry if there's already a similar topic. If so, feel free to lock this thread.
