This is the train (4-4-0 locomotive and 3 cars) from an American Flyer Al Aboard Pioneer 600 train-set (#20811) from 1966. I came across this complete American Flyer All Aboard set many years ago over-here (Netherlands) and still wonder how it ever came here. The shipment of the very large box must have cost far more then the value of the contents I assume. As you can see the train still runs.
