American Flyer wasn't alone in using sharp track pins. Over the years I've seen plenty of tubular track with track pins that looked like the pointed end of a nail. Judging by the way the pins were inserted, they did not look to be user installed.
I had also concluded that the pins were shipped this way by the manufacturer, although, as you state, each of the pins literally looks like the point of a nail.
