It's possible that New Orleans may be taking part in the Viewliner refurbishment program. Thus, one of the first sleepers to be refurbished was headed on its way down to the Big Easy. Or it was a deadhead, but who knows. Afterall, Amtrak can be very unpredictable.
Anything of course is possible, but I don't think that NOL is setup for that type of work. To my knowledge, they've only got engine shops down there. At least that's all I saw when I was there late last year.
They might be able to do light maintenance on a VL or perhaps a quick patch to allow a VL car to head somewhere for a real fix, but again I don't think that they are setup for heavy car maintenance.
