Being that I mainly model the AT&SF in the 1948-1951 time frame I don't have many books on other railroads. I have a side interest in the Southern Pacific, which mostly comes from a childhood fascination with 4449 (whi h I own a MTH Premier model of). I have 3 Southern Pacific locomotives on my roster; 4449, a Baldwin AS616, and a FM H-24-66 Train Master. I'd like to add another Southern Pacific steam locomotive to my roster in the next year or so for freight use. I don't have room for a big 2-8-8-4 or 4-8-8-2 cab forward so I was wondering what non articulated steam locomotives were commonly assigned and in use on freight trains on the Southern Pacific in the 1948-1951 time frame. After conducting some basic internet searching it appears that the GS2/GS6 class Northerns, MT class Mountains, and Southern Pacific class 4-10-2s were used on mainline freight trains. Am I missing any types? I'd appreciate any help from some knowledgeable Espee fans.
