Reply to "Shorts Between a Brass Steamer with a Metal Coupler on the Pilot..."

For locomotives, freight,  and passenger cars where the mounting pad is on a metal underframe I mix and match plastic and metal Kadee couplers and pockets so that a metal Kadee coupler is  never mounted in a metal Kadee pocket (I use metal and plastic Kadee's interchangeably).   For steam locomotives used in switching or local freight ops I use a Kadee 804 plastic coupler with a trimmed/reshaped shank mounted in the pilot without draft gear.   If you have a large number of Kadee metal couplers with metal pockets and need additional plastic ones to do the "mix and match" you can purchase plastic draft gear pockets directly from Kadee.
