Something I have meant to ask for awhile:
What purpose did the tank car dome serve? Tank cars used to have domes. Now they basically have a valve and fitting. What changed technologically that they now are dome-less? I have guessed that the dome was for air space to allow for expansion/contraction, but not sure if I am correct.
