Southern Steam to New Orleans

[Overmod]

What else did they have that would pull passenger consists of the required size in those years?

I'm sure someone here is a Southern aficionado and knows the progress of dieselization on those trains, which I don't, but that's the only thing that's a practical alternative.  To my knowledge Southern never even considered larger or more modern passenger steam power than Mountains once there was a diesel alternative... even some of the fairly wonky types that Southern acquired in the '40s.

Did any Southern Railway 4-6-2s and 4-8-2s ran to New Orleans in the 1930s and 1940s
