How did people on the trains use the bathroom during the holocaust?

Answer: They could not use the bathroom. The Jews were packed so close together in the box cars that there was no room to move. And no bathroom. The urine just thickled down their legs to the floor.

Explanation: The Nazis we're not consideing the comfort or health of the Jews who were rounded up and transported to concentration camps to be killed and their bodies shoved into mass graves they were forced to dig for themselves - or gassed and incinerated in massive ovens during the Holocaust. The unsanitary train ride was only the beginning if the indignities and atrocities they suffered.
