Interesting to see a 1943 build date on that USOX tank car. I did not know that design was used after the 1920s. I’m not used to seeing an AB brake system under a tank car like this.

     Used in the 1920s for heavy acids like nitric and sulfuric, supposedly to let vapors sink out the bottom. Or something. That explanation always seemed lacking to me. But they were common at one time.
