I think a large percentage have been refurbished, too. I haven't seen any retinal-burn orange seats in the roomettes for awhile.No, about 85% of the I's have been refurbished to some degree. The earliest cars through the program had less work done on them and a few did not get the new, sleeker modern restrooms.So have all the superliner I cars been refurbished? And is the superliner ii the one with the bathroom problen?
As for the vacuum problems for the toilets, the II's seem to experience it more often, but it can still happen on the I's too.
