The Pacific Coast Borax Company, the former owner of the Tonopah and
Tidewater Railroad, Later American Chemical & Potash, (Later Still
U.S. Borax after the scope of this list) had a small but growing
fleet of Pullman built NAHX 2003 cube covered hoppers to ship Sodium
Borate and other Borax products from their Boron, CA plant. (I would
welcome any information about any General American or other
additional cars.) The highest volume destination was their Pier A
plant in Long Beach. There is circumstantial evidence to suggest
that they also used ATSF marked cars, which probably would have
included 2893 cube PS-2's by the end of the '50's. These cars
however did not have "shelf type rungs" on their end ladders.
PCB/ACP also shipped bagged product in boxcars.
the manufacture of said items; and can provide enlightenment?Thinking
