Read your post on diatomaceous earth. I'm modelling
the ESPEE coastline between Santa Barbara, and
Guadalupe, including the Lompoc branch circa 1964.
I chatted with someone who worked the branch in the
sixties, and he told me that it was shipped mostly in
boxcars.I noted that the title of this chat was about
western hoppers. ESPEE ,like the other western
roads,had large fleets of GS gons That did the work
that hoppers did in the east.I'm sure some of ESPEE's
hoppers did stray east. I never saw many hoppers out
on the coast.

diatomaceous earth in
SP served the world's largest deposit of
California, and that stuff was shipped all overthe world. It
has many uses -- including its key use inDYNA-mite.
Here is some diatomite (diatomaceous earth) info
from the late 1940's:
Although Oregon, Nevada, and Washington were
producing small amounts,
California was the largest producing state, with the
located near Lompoc. Both the Johns-Manville
Products Corp and the
Dicalite Division of the Great Lakes Carbon Corp
appear to have worked
this deposit, with Great Lakes Carbon also working
the second largest
deposit in the state near Walteria.
Uses were grouped as follows: (1) filters, more than
1/2; (2) fillers,
1/3; (3) insulation, 1/8; (4) lightweight aggregate
Filters for all types of liquids are made in several
various specific purposes. Powdered diatomite is
used in fillers
where a chemically inert lightweight mineral is
materials include saw brick and manufactured pressed
and calcined aggregate are also made and sacked.
abrasives and dental powders are minor uses for
Processing of the diatomite was done at the quarry.
Natural brick was
sawed and kiln dried; pressed brick was manufactured
aggregates were made and sacked. Sounds like mostly
boxcars to me for
the brick and sacked products, although no further
mention is made of
the filtration market.
Great Lakes Carbon trucked the material from Lompoc
to Walteria where
it was processed with material from the mine located
