Not quite. The gons I saw were not as tall. The solar panels were mounted on a short mast, tent like on each end of the cars. They were oriented 90 degrees from the other end.
The thought of them powering some type of opener is interesting. From my vantage point, I could not see the bottoms of the cars. I could not tell if they had bottom dumps or not.
