Not sure but with the hand brake you control your speed. You can actually stop if you wanted, but they tell you not stop on the track. It's fun and I hate roller coasters.

I control the your own speed
30 mph but you control how fast you go with hand brakes
It's not overly fast, it does move along though. You, yourself kind of control the speed, you have a braking system you can control.
