    The resort blog says the runaway mine train reaches 24.9 mph (40 km/h). RCDB lists the coaster and does not say a speed, so the park figure is the one that is used.

  2. The number on the row

    The qualifier is official because the resort published the number. The same blog's 29.8 mph (48 km/h) line is the closed Space Mountain and is not this ride.
