ABSTRACT OF THE DISCLOSURE A selectable dolly vehicle conveyor system having spaced dollies mounted between two drive chains and normally moving on a lower track concealed beneath an upper track. A ramp for shunting the rear part of a dolly to the upper track to push a vehicle, operates only when both the front wheel of such vehicle holds depressed a treadle switch located beyond the ramp and at the same time the front roller of such dolly has passed the ramp and depresses a dolly treadle plate on the lower track. This permits the front part of the dolly to pass the ramp unobstructed and ensures that only the rear part of the dolly will be shunted to the upper track, even though the front and rear parts of the dolly are longitudinally aligned.
