carolinian 79

A question that's piqued my interest today was where does the 79 Carolinian turn around at Charlotte to face NYP as 80, I know for a fact they don't use the wye at Pineville anymore since that's 10 miles down the line and extremely time-consuming.

Hi, I’m taking the Carolinian for the first time, only for a short ride but chose an assigned seat in business class. I was wondering if anyone knew where the business class car, seemingly its only one, is located on the train? Is it the first car or the last car at the back? Just so I know...
