I searched the Lionel site and could not find them ,, so I sent an inquiry e-mail to Lionel this morning..
I do like the idea of tagging the 'hot-wire' of each car together as over the 7-cars I have .. it would be extremely stable. I do like the lamp brightness level with the diode that I added to each car .. if I tie all the hot wires together on all 7-cars, I will have to double check the polarity of the diodes I put in to ensure they are all in the same direction .. I also have to ensure that I put the diode in the wire feed from the center rail .. otherwise .. YIKES
BTW .. I do like your thoughts on small or micro 2 or 3-wire connectors.. I should have used them on all of my buildings, in lieu of wire nuts or soldering/shrink tube .. it makes is easier for any repairs or efforts that may require me from removing them from my layout.. I saw some nice 2 and 3-pin connectors on Amazon .. some 22 gauge and some 28 .. pending what you are connecting. I may buy some and re-introduce them into my layout
