There is a shower on the lower level of the Deluxe Sleeper as it's still called, even though Amtrak no longer calls the larger bedroom a Deluxe bedroom.
The lower level of the Deluxe sleeper is identical in all ways to the lower level of any Superliner II sleeper. It's only the upper level that is different. There were originally six of these cars used exclusively by the Auto Train. Thanks to that bad derailment in Florida back in April of 2002, they're down to five now. They are the Palm Bay #32500, W. Graham Claytor, JR. #32502, A. Phillip Randolph #32503, Palm Harbor #32504, Palm Springs #32505.
The Palm Springs #35501 is still listed as wrecked and out of service. Considering how valuable these cars are to Amtrak and the number of years that it has been out of service, I'm betting that this car is beyond repair and just being used for parts before eventual scrapping.
