When searching for trains from New Orleans to Chicago, there are 2 trips. The direct trip on the City of New Orleans, which takes 19 hours,or taking the Crescent to Charlottesville, Va and then the Cardinal to Chicago with a about a 3 hour layover, and a total time of an extra day. Is it worth the extra time? Is the scenery good? What's the station like in Charlottesville? Is the 3 hour layover enough time most of the time?
