Re: interesting COSX tank car in MR

Please help me and possibly others understand how a single compartment
tank car can be converted to multiple compartments. You refer to a
diaphragm, the wall between the compartments, which I know as a
"bulkhead" with the ends being "heads." Bulkheads could be both single
and double (air space between compartments).
Now, how did they do it? The word diaphragm throws me. Did they
assemble the bulkhead inside the barrel after putting it in through the
dome opening in pieces (doubtful)? Or did they make the conversion by
removing one of the heads (ends of the barrel) and slide the bulkhead
(partition or diaphragm) in the end? I suspect this was the method.
And were rivets were used for both the new bulkheads and the new dome?
I'm not trying to put you on the spot, but if anyone will know the
answer(s) you are the guy.

and information for modelers of the mid- to late '40s. That MR used
only one of the photos is typical of their once-over-lightly approach
to prototype modeling; sure wouldn't want to overwhelm the train set

Two compartment tank cars that were converted from single compartment
cars by adding internal diaphragms and a smaller dome at one end only
weren't all that rare; I have a number of photos of them. It was even
more common for single compartment cars to be converted into three
compartment cars by adding diaphragms and domes at both ends while
leaving the original, larger capacity center dome in place.
