We were on a “sold out” SWC 12/20 FUL/GBB I had been checking loads about 2 weeks out it started to show sold out. I was amazed once onboard the first 2 days the trains 2 coaches were only half full. Sleepers a bit more. Diner was dead, a couple meals my family was only one in there. Yes some people ate in rooms, but still it was dead employees, just sat around. 1:15pm lunch diner to ourselves on a sold out train 4 days prior to Christmas. Talking to a talkative conductor on day 2 he said the “light sold out“ trains started when they removed the 4 cars from the consist, (2 coaches, 1 sleeper and bag car). The bag car only makes a difference in spotting stops at stations. But running such a small train requires them to hold back bookings for corridor passengers on both ends KC-CHI corridor and lessor extent ABQ-LAX. Not having a cut out car KC-CHI really is affecting ridership apparently. Just like he said on the morning of 12/22 in KC a boatload of people got on in both coaches and sleepers.
Im pretty sure the TE still has the STL-CHI coach but shares similar issues to the SWC. The system is really being set up to fail in my opinion.
