Mechanism

Why it's so fast

Magic Kingdom's Space Mountain runs both tracks at 27 mph, an indoor coaster whose speed comes from the lift, not a launch.

Speed

Tracks
Alpha and Omega
Height
90 ft

  1. Alpha and Omega

    RCDB and Coasterpedia say 27 mph for both the Alpha and Omega tracks, so one row covers the building. RCDB says a height of 90 feet. The two sources disagree on which track is longer, so length is not a separate figure.

  2. The slow end of the list

    TRON, in the same park, is the fast Magic Kingdom coaster. Tokyo's Space Mountain closed July 31, 2024, and is not this row. Anaheim's Space Mountain is 32 mph and is a different building.

The fast Magic Kingdom coaster is TRON Lightcycle / Run.
