Hello all,

To broaden my original question a bit - I would also greatly
appreciate any references to works that discuss the transition from
ice to mechanical reefers in terms of both design and operation. I am
not interested in this for modeling purposes, but to better understand
the significance of preserved cars.

I have found personal recommendations to be invaluable in doing
similar research In doing similar research on other railroad topics.
In indexed articles (whether it be the model train magazine index or
something else) it is difficult find articles that present an in-depth
analysis.
