Standard locomotive draught gear
Originally prepared for the W kit, this casting contains detailed scale draughtboxes, couplers and a hook.
Coupler holes are pre-formed, and one coupler has the draught pin cast in place. The castings can be made to self center by gluing 2x 1.0mm x 0.5mm magnets into the cast in recesses . magnetic centering provides good performance without risk of excessive force derailing wagons.
Coupler retention is intended to be via a 1mm screw.
