Mr.FSS is correct about the bed sizes. My wife and I took a May round trip on the EB (CHI-PDX). We shared the lower bed and never had the attendant prepare the upper. I am 5'10" (170 lb) and my wife is 5'2" and we both fit on the bed with plenty of room. Even after 39 years together, we still like to sleep close.
We had the refurbished sleepers going and coming. The one out was great, but the return one had already been worn out. Maybe it was one involved in the derailment a couple of months ago. The separate chair that usually is movable was bolted to the floor and wall. You couldn’t move it or adjust the back. It was very uncomfortable.
The bath is a great improvement over the old style and the sink faucets stay on a few seconds after being activated making it easier to wash hands and rinse out a wash cloth.
We were the last of 13 cars on the train and I took advantage of the view from the rear. It was great while going through Glacier NP.
