A toy vehicle includes a main body assembly supported for movement on wheels and having opposing right and left lateral sides, opposing front and rear ends, and opposing top and bottom sides extending between the lateral sides and the ends. The combined opposing right and left lateral sides and opposing top and bottom sides of the main body assembly define a slot that extends through the toy vehicle. An arm is provided for lifting at least one track segment from a level below the main body assembly up and into the slot while one or more other propulsion elements are provided in or around the slot to engage and move the one track segment entirely through the main body assembly along the slot from the one end of the vehicle to the opposing end of the vehicle.
