Journey to the Center of the Earth is using the same ride system as TestTrack and basically features two segments. First a dark ride style slow paced journey to the center of the earth which is the equivalent to the indoor part of TestTrack, even so much much better as with fantastic sets and scenes. In the last scene of that part guests encounter the lava monster and speed to safety through dark tunnels, shortly plunging out of the volcano into the light - which obviously is the equivalent to the outdoor highspeed segment of TestTrack.
Personally I enjoyed the attraction very much and think that it made much better use of the ride technology than TestTrack as it manages to tell a great story and integrate the ride technology features into that story telling neatly.
Rocket Rods and Test Track basically use the same system, although the vehicles are quite different. The cars have all the componants and are "smart" in that if they get too close to eachother, they will slow down/stop accordingly. This is was ultimately killed Rocket Rods as the cars were always going into a cascade and the entire system would have to shut down.
Dinosaur is the same ride technology as Indiana Jones Adventure - Temple of the Forbidden Eye at DL. Trust me...with the potential of what Dinosaur COULD have been, all the small details, we got the VERY short end of the stick. THEY have real fire and the rat room and poison darts. WE have sharp turns in a dark room. Yee freakin' ha.
I'm still happy with what we got, I don't like comparing or thinking what could have been as long as it seems to be a high budget animatronic ride. We don't get any of those any more. The only thing I think "what could have been" is Epcot's Future World, its a shell of what it used to be (or however that saying goes).
Fire isn't anything special to me but I would like to know about the poison darts
Well unless I am mistaken they are basically Rocket Rods vehicles with those large Drill things on the front and a few extra pieces added on. Strictlyl body wise- I don't have any idea what type of drive system is used. But the Rocket Rod body was basically a bare bones version of these vehicles. Both were capable of variable speeds and I believe I've been told that the JTTCOE vehicles could raise up in the front (Just about the one cool thing the RR could do).
The attached picture doesn't prove much, but it does show the large wheels in the back and the passenger seating is similar.
Journey to the Center of the Earth is a killer ride. Very magical, and far better than Test Track (but then GM would not have sponsored Journey!).
The size of the final AA figure of the Lava Monster is HUGE HUGE HUGE and, man, does the car take off after that! There are also some good dips, which Test Track lacks.
It's funny: I was standing in the center of Mount Prometheus in Mysterious Island, dead center of the volcano, and I heard this whizzing around me. At that moment I realized that the vehicles from Journey speed around in a circle exactly the same way that the Test Track vehicles do at the end of the ride, but here it occurs inside the volcano.
