They do not have any open window coaches. The vestibules are about the only place you can catch the air. One thing they did i did not agree with was they either sold or traded away "Man O' War", which had those big open windows at one end. It was great for watching and also shooting video. also liked the history of that car, it was towed by 611 for many a mile! (As well of 734, later of course)
