How much (gallons, liters) does a typical railway tanker car hold?

Your basic tanker car holds 22,800 gallons, though there are many different designs. But you can't fill it full. You need to give it some head space, called "outage", and that varies on what you're shipping.

It's 5% for hazardous materials and 1% for non-hazardous ones by default, and specific materials have other standards. You need to give it some room to expand with temperature, or the whole thing may explode. Sources: https://www.procor.com/helps/how-read.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
