Around 1940, Pullman advertised berths for as slow as $2.65.   
   However, that didn't include the higher first class rail fare,   
   which was about $2.60 more.  There was also 10% Federal Tax.   
   So, a Pullman berth cost about $6 back then.  With a rough   
   inflation factor of 15, that comes to $90 in today's dollars,   
   not something that cheap.   
      
   I've heard that Pullman accommodations and dining cars were   
   generally beyond the means of working people back then.  Except   
   for an extremely rare trip, they made do with a sandwich   
   brought from him or sold from a vendor, and slept as best as   
   possible in a coach seat.   
      
   In the 1940s, the section sleeper, though extremely common,   
   was falling out of favor; if a roomette was available, single   
   travelers preferred that.  Upper berths were very unpopular.   
   Pullman began to push the "single occupancy section" which   
   was a lower berth with no one in the upper.
