Anyone been on the Pere Marquette #371 or Wolverine #352 since they started booking 1/2 the trains? I see the app now shows what % full the train is, which is great. I am a regular rider who has not been on since end of February and am thinking of getting on 371 and 352 for round trip end of September/beginning of October. At 1/2 full and in a Business Class seat I would expect it to be fairly safe but just curious if anyone has been on and how clean the trains were? Thanks! Oh and how was Chicago Union Station??
