I am not an expert in these matters........so.
I believe that many technologies combined to eliminate some domes. Tank bodies are no longer riveted, loading, and unloading facilities have improved, some tanks are insulated, so heat or cold, have less effect on the tanks contents.
The evolution ( there's that evil word again ) process has been slow, domes have been changing over time, and are either much smaller now, or gone completely, as the need for them changed.
The choice of tank cars can run from all domed cars, to dome-less cars depending on what era is modeled, and what product the car is designed to carry.......yeah, another "rivet" to count, and more research to do.
Fortunately, I don't dislike doing the research.
RESEARCH; n; v; The act of finding information; The dominant excuse for procrastinating.

We always learn far more from our own mistakes, than we will ever learn from another's advice.
The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
