3M had an operation near COrona, CA. The ATSF Elsinore branch from PorphyrySome of the 3M box cars were used to transport diatomacious earth from
Corona to some place in Minnesota or Michigan. Others were stenciled to be
returned to Copley, Ohio when empty. They were a common sight on the Santa
Fe's Los Angeles Division en route to and from Corona in the 1940s and
early 1950s. I have a couple of photos of them. The roof "hatches" were
actually just small round affairs; apparently the cars were loaded through
pipes inserted in these openings.
