G B....although the interior of the double decker train you watched on tv could be altered to sitting passengers only the train leaving Chicago would possibly have been a long distance sleeper. These trains carry passengers accommodated in the main, two to a compartment, seating converting to full sized bunks. Plus dining cars, observation lounges, shower rooms, toilets kitchens and all supplies fuel and water, that is the reason they are so long. The one I travelled on from Seattle to Chicago was double decker as tunnels were built for them. The train from Chicago to NewYork single decker because tunnels could not be altered to cope with them.
p.s. What I am saying is, those trains are not ram jam full of passengers, no standing room at all.
