Drummer Dave, I question those ammeter readings you post above.  They sound way too low for old postwar equipment, especially with incandescent lighted passenger cars.  Are you sure you're using a good quality AC ammeter?  Running 2 freights and a string of LED-lit cars, about modern 6 motors running, I pull about 8 amps from my Z4000.
