Technically yes, but you have to apply air friction as well. A hammer will hit the ground at the same time a feather does, but here on Earth, air friction slows the feather down much more than it does the hammer. It is possible for a very fat person to slow down the ride. The resistance between the track and the wheels may increase enough to slow it down. You also have to consider aging to the ride. Rust and bird-poo could slow it down too.
But most of that is just ramble. You probably shouldn't listen to me anyway.
