There's an article in the May 18 edition of the Travel section of the NY Times on travel by restored Pullman car between Chicago and New Orleans. I met an Amtrak conductor last year who was planning to take such a trip. I'm heading to New Orleans for a wedding in the spring - considering going by rail.
Here's a link, if it works. I'm sure the general topic has been discussed here - just wanted to pass along today's article. Mentions that they play to add service between New York and Chicago, via both the Cardinal and the Lake Shore Limited.
