| Abstract: |
A turntable bearing tracks at a switching point in an amusement ride course, or other vehicular path having tracks, utilizes two linear induction motors, one for rotating the turntable and one for latching the turntable at selected rotational positions. The linear induction motors are mounted beneath the turntable and operate with an extremely high degree of reliability.
