I’ve read that the Southern Pacific allocated 4 new GS-1 class 4-8-4s to it’s Texas & New Orleans subsidiary. I also found another source stating there were a total of 11 4-8-4s that operated as T&NO units, so I’m guessing they either sent them another batch (or batches) of new locomotives, or they just transferred some from the Pacific Lines. What were they used for on the T&NO during their operating lives? Did they start out as passenger power for the Sunset Limited before diesels? Were they mostly freight engines? I would assume they ended up being freight engines regardless of their original purpose in their final years. Or were they used as dual purpose power from the very beginning?
