First of all, the book is about single sheathed box & automobile cars. The X29's were considered of all steel construction.
The distribution of ownership of total boxcars, all-steel & steel underframed boxcars was not the same. SUF boxcars include double sheathed as well as single sheathed.
In terms of ownership of the Total Boxcar Fleet owned by Class I RR's in the US on 12/31/1940, 39.4% were owned by RR's in the East; 17.2% in the South; and 43.4% in the West. Of the Total All-Steel Boxcars, 62.6% were owned by RR's in the East; 15.0% in the South; and 22.4% in the West. Of the Total Steel Underframe Boxcars, 27.8% were owned by RR's in the East; 16.4% in the South; and 55.8% in the West.
The majority of Steel Underframe Boxcars (55.8%) on 12/31/1940 were owned by Western Railroads. Assuming that the ratio of single to double sheathed boxcars was the same in each the Eastern, Southern & Western Districts, that the vast majority of single sheathed boxcars were owned by Western Roads in an SP Los Angeles Yard should not be that much a surprise particularly when many of the SP cars were probably in temporary storage awaiting for the economy to expand so that they could be loaded.
That said, the economy for boxcars was not nearly as national before WW II as it was after WW II. In parsing various pre WW II wheel reports and other documents, there appears to be a much higher percentage of loadings in home road boxcars before WW II than afterward.
Hope this helps explain why Richard could find so few photos of Eastern Single Sheathed Boxcars in LA before WW II.
