Auto Train is a little different because of no station stops. But there are still OBS employees assigned to "patrol" the Sleepers, Coaches and food service areas all night long on the Auto Train.My most recent experience with a SCA was on the Auto Train in January. She politely made it clear that her work day was over at 10:00 P.M. or 11:00 P.M. (I don't recall accurate which) until 6:00 A.M.
