The winged wheel from ancient times usually was shown as a circle with wings, and the circle is thought to represent the solar disk. Spokes, when present, are thought to represent rays from the sun. Alternate explanations have the spoked circle representing the wheel of the chariot of the sun. As far as I know, none of the ancient representations show a railroad flange on the wheel, but I could be mistaken...
I'm sure the ancients didn't include a flange. However, that doesn't preclude one from being a derivative of the other.
