Box Car Door Markings Question


Nelson Moyer
 

I built a couple of Westerfield CB&Q XM-17/18 kits recently. The decal sheet includes a small white square approximately 5 or 6 scale inches square, and photos show the square painted in the lower center of the wood door. Does anyone know the significance of that square, and what range of years was it applied? A post to the CBQ group went unanswered.
