<P> The coaster accelerates from 0 to 57 miles per hour in 2.8 seconds ( making this the second - fastest attraction at the Walt Disney World Resort , behind only Test Track ) . The riders experience 4.5 G as they enter the first inversion , more than an astronaut does on a space shuttle launch . Both versions of the attraction feature five trains , although only four can run at one time . The remaining train is kept in backup while being serviced ( each train is rotated out periodically for safety reasons ) . </P>
