1921 – 1956 – SP 745 hauled mostly freight, but occasionally passengers, from 1921 through 1956. Although it was always painted “Southern Pacific” or “Southern Pacific Lines”, it actually worked for SP subsidiaries. The state of Texas had a law that required railroads operating in the state to be based there. SP owned the Galveston, Harrisburg, & San Antonio, and sent 745 to work for it. Later 745 worked for another Texas-based, SP-owned line, the Texas & New Orleans. In these roles 745 operated mostly between east Texas and the east end of the SP system in New Orleans.
