Is it too late for me to chime in here? "Diaphragm" is a fabricator's
term, possibly now archaic, for a web that spaces structural members.
Used in this manner, any built-up bolster consists of four pressed
steel diaphragms, top and bottom cover plates, a center filler and
possibly end fillers. The usage of the term is correct, but hardly
unique to the Standard Tank Car Co. bolsters.
