Abstract
A model railroad coupler centering system includes a draft box and a coupler. The coupler includes a coupler head and a coupler knuckle. An elongate coupler shank extends between the coupler head and a coupler mounting structure. The coupler mounting structure includes a mounting plate, which may have forwardly diverging sides thereto. Plural centering springs are fixed on each side of the coupler mounting plate such that when the coupler is centered, the centering springs make touching, non-flexed contact with the interior of the draft box and, when the coupler is pushed off-center, one of the centering springs makes flexed contact within an interior side of the draft box and the other centering spring does not make any contact with the other side of the draft box.
