Rolling Stock Recommended weights

To ensure reliability of train movements on the layout all rolling stock will be properly weighted as per NMRA Recommended Practice (RP) 20.1. The following table provides a quick reference for both HO and HOn3 (narrow gauge) to calculate proper weight based on the scale feet of the rolling stock. All weights are in ounces.
