Since the absolute minimum radius on the layout is now 1200 mm - just one curve in the passenger section at Samedan - it was time to check if body mounted Kadees would be possible.

Yes indeed, with a few extra provisions.

Allow the coupler to pivot around the mounting screw, restrict the pivoting by modifying the mounting pad, add a tang to attach a centering spring if that should be required. A dished plastic washer provides minimal friction.

Coupler heights are supposed to match the Kadee coupler gauge.
