I was on the westbound CZ Thursday and was really impressed by the noticeably clean interior, I remarked to folks at my destination how crazy clean the 40-year-old car looked but frustratingly on the return trip today (lnk-chi) the car looked really skuzzy, and it was even the most updated version of the Superliner coach. Using my one trip data set, are: they having issues ramping up to daily service, California to Nebraska riders are slobs, the CHI Union Station cleaning crews just really good at cleaning, or I was lucky once.
