A magnetically actuated coupler assembly for model railroad rolling stock is provided. The coupler assembly includes a drawbar having first and second ends. The first end includes an aperture defined therethrough adapted for mounting in a coupler pocket on model railroad rolling stock. The second end includes a coupler head. A coupler knuckle is pivotably mounted to the coupler head by a magnetically actuated pivot post. A first coil spring alignment pin is located on the second end of the drawbar. A second coil spring alignment pin is located on the coupler knuckle. A coil spring is mounted between the coupler head and the coupler knuckle on the first and second coil spring alignment pins for resiliently urging the coupler knuckle to a coupled position. At least one of the first and second coil spring alignment pins includes a coil spring retainer which engages at least a portion of the coil spring to prevent the coil spring from becoming dislodged from the at least one of the first and second coil spring alignment pins.
