Your post prompted me to pull out that article from my archives. Hard to believe Pullman had 9000 employees at its peak. Their attention to detail, training, and supervision resulted in always reliable good service. I wonder if it's possible for Amtrak to achieve that level of consistent service.
"Pullman developed a standard method or regulation for
almost everything that could occur aboard a Pullman car.
Every detail of hospitality to the passenger was covered
in minute detail. Books of instructions and rules also were
issued for (Pullman) conductors, attendants, maids, barbers, and bus
boys. It was little wonder that fbr decades former Pullman
employees were sought for service in the White House and
in the finest metropolitan clubs and hotels."
