On the CZ trip to CHI this past Sunday three original California Zephyr cars were attached. At CHI those cars were detached and put on Amtraks CZ. There was a rear observation/lounge car, a dome car and a sleeper. They were detached at DEN. It was some kind of private rail car trip with all of the trimmings for a group of "high rollers". I spoke with one of the passengers for a moment and he reported that the chef and service were top notch. The open windows in the sleepers seemed to indicate that the rooms were not that much better than what is on Amtrak but its a sure bet that the lounge and dome were luxurious. Anyone know anything about this rail trip?
