Ball bearings are contained in each race that are rotatably engaged between the race open portions and the grooves on the sidewalls of the track. The car further has retaining means for holding the ball bearings in place along the open portion of the race when the car is removed from the track. The retaining means are movably received by the track groove, and otherwise allow for free rotational engagement of the groove by the bearings.
