The electricity that powers the ride's Linear Induction Motors comes from a 100-yard-long room built beneath the coaster. Hidden from the public, it houses a 25-megawatt transformer that feeds a 5,000-horsepower variable frequency drive. The frequency and power output is adjusted for every launch in order to compensate for weight variations in each train's passenger load. Nearly two dozen sensors measure the trains' speed during the launch and vary the power applied to achieve the desired acceleration rate.
