Q. How many people were shipped on a train to go to the concentration camps?

Hi Olivia -

Thank you for your question. On the VLC, in the Britannica for Middle School databases, I searched concentration camps and the holocaust and discovered that millions of people died in the holocaust. Most of them were shipped there by trains. You may read up on it further in Britannica. Here is the link to more information, images and a video -
