Ah I see. I didn't know that. The last time I took the CZ the sleeper and diner cars were at the beginning of the train, and I guess I just assumed that was always the case. Thank you for sharing this!I think it's essentially random based on how the cars are placed in the yard when they are building the consist. They do keep similar cars together, and often use the service cars (cafe/dining) to split the coach from sleeper, but which set gets the quieter location at the end of the train is mostly random, just like which side the bedrooms are on.
