ABSTRACT:
A track construction for a self-propelled vehicle includes a pair of longitudinally extending track members connected in transversely spaced relation by arch-shaped yokes which extend upwardly over the track members and from which a conductor rail is suspended in vertically spaced centered relation with the track members, the conductor rail being engageable by collectors on the vehicle for powering a vehicle drive motor. At a junction between main and branch line track members and conductor rails, co-axially pivoted, independently movable, track and conductor rail switch tongues are mounted and are interconnected by a differential motion transmitting mechanism which causes one of the switch tongues to move between main and branch positions in response to a different extent of movement of the other switch tongue between such positions.
