Reply to "HELP! How do I wire the operating couplers on a postwar Lionel UP 2033 from 1952?"

They are only activated momentarily and thus really don't have the time to overheat. If it is overheating and not being activated, you definitely have a wiring issue of sorts. You didn't inadvertently connect it to the center rail pickup and not the sliding shoe, did you?
