Abstract: An apparatus for magnetic spin control includes a main chassis, a passenger chassis, a circular magnetic array, and a chassis-mounted fin. The main chassis is configured to ride on a track. The passenger chassis is rotatably supported on the main chassis and the passenger chassis is configured to support one or more passengers. The circular magnetic array is coupled to the passenger chassis such that the passenger chassis rotates with the circular magnetic array. The chassis-mounted fin is coupled to the main chassis and extends into a magnetic field of the circular magnetic array. The chassis-mounted fin includes a conductive material and operates as an eddy current brake to dampen rotation of the passenger chassis with respect to the main chassis. The chassis-mounted fin extends into the magnetic field and leaves at least a portion of the magnetic field unobstructed to allow a track-mounted fin to pass into the magnetic field.

Abstract: An anti-rollback apparatus includes a lock arm, a rod, a pawl, a wheel, and a one-way bearing. The rod member is pivotably coupled to the lock arm and the pawl and one-way bearing are coupled to the rod member. The pawl is shaped to selectively engage teeth on a an anti-rollback plate. The wheel is configured to roll on a surface of the anti-rollback plate. The one-way bearing couples the wheel to the pawl. The one-way bearing allows the wheel to rotate freely in a first direction and locks the wheel in relation to the pawl when the wheel rotates in a second direction to force the pawl to engage the teeth.
