Can some knowledgeable person confirm that PS1 boards are universal to all PS1 locomotives? I'm looking to replace a PS1 board on a Premiere Class A articulated locomotive and I've seen some posts mentioning that the articulated engines had different boards than the ridged frame ones. Can the broken board in my Class A be replaced with one from a 4-6-4 Hiawatha? Is there a difference between Premiere and Rail King PS1 boards? Any info would be greatly appreciated.
