Wayne, this says what I am trying to point out : Most American Flyer "S" and "O" engines were designed to run on AC or Alternating Current. Although, the motors are what is referred to as "series wound", so they can also operated on DC or Direct Current. Maximum voltage is 15 to 17 volts. http://www.rfgco.com/tips.html?trans.html
