The three compartment car appears to have been a 6,000 gal
single compartment car converted to three compartments. Such
conversions were fairly common (more often, though, on 8,000 gal.
cars), especially on GATX cars.

How would they do that? I suppose they could take off the heads and
slide
the new ones inside the shell, but my guess is that the inside was
far from
a perfect cylinder which would make "sliding" heads in and getting
a good
circumferetial seal very difficult.















Nevertheless, that's exactly how it was done, Kurt. I've sometimes
thought that they probably un-riveted the top seam, as well, since
they would have had to cut new openings for the end domes and bore
new holes for the dome flange rivets. But I've never found either a
photo or a witness's account of exactly how it was done.
