Abstract: A motor driven transporter for transporting a moving toy object over an interruption in a slot track system where the interruption is between an incoming track segment and an outgoing track segment. The transporter includes a dock having a holding member for holding the toy object on a track surface of the dock and a restraining member for restraining the toy object from moving forward and backward on the dock, and a motor for moving the dock linearly or through an arc of up to 180° between the incoming track segment and the outgoing track segment.

Abstract: A toy object and slot track system includes a plurality of track segments each having a retaining slot provided thereon and defining a slotted track surface. The track segments include straight, curved and twisted track segments connectable to form straight and curved tracks with slotted track surfaces facing upwards and/or downwards and twisted tracks, and concave/convex track segments connectable to form loop-shaped tracks with concave/convex slotted track surfaces facing inwards and/or outwards. The system includes at least one toy object having first and second protruding pins for slidable engagement along the retaining slot. At least one of the first and second protruding pins has a free end portion retainable within the retaining slot such that the toy object can move along the tracks without falling off under gravitational pulling force.
