Dont know? Accelerator coasters and rocket coasters are the same thing. Rcdb is a great website but those little things are not that big of a deal. Maybe its because they administrator of the webpage noticed ever body was saying accelorator instead of rocket coaster, therefore more people would know what they ment by accelerator.
did anyone also notice that in RollerCoaster tycoon 1. you can add boosters at any flat piece of track. but then in rollercoaster tycoon 2. You cannot ad boosters? why?
I noticed that too. They probably did it because the first accelerator coaster was TTD, and it went really fast and very high so they called it rocket. But now there are some accelerator coasters that don't go as high, like Rita Queen of Speed and Storm Runner.
According to Intamin's latest promotional materials they are still called Rocket Coasters. (unlesss I picked up an outdated brochure, which is possible I suppose)
Favorite Wood Coasters: The Voyage, Ravine Flyer II, Thunderhead, Balder Favorite Steel: Voltron Nevera, Steel Vengeance, Expedition GeForce, Olympia Looping Parks visited: 232, Coasters Ridden: Steel: 894, Wood: 179, Total: 1073
The term "Accelerator" is much more popular amongst European enthusiasts. "Rocket Coaster" is very popular in North America. The only reason is probably that Accelerator is a more recent term, and Rocket Coasters didn't come to Europe until recently.
