Well went to the NMRA site and looked under the standards and recomended practices and found that for On30 calls for HO couplers and the same height from rail to coupler as HO where as On3 sits a bit higher 35 790_smiley_picking_a_fight 35

here is a link to the standards for couplers

Do why is the kadee On30 height gauge sold with an On3 coupler? :?
