How did Levi describe the journey on the train to Poland in his memoir, Survival in Auschwitz?

Levi records that everyone was boarded onto the transport trains, and the men, women, and children were crowded together like cheap merchandise. Though they were loaded early in the day, the train did not move until evening. The train traveled slowly, with long, unnerving halts. Through a slit they could see the countryside as they passed. They suffered from thirst and cold. Everyone was hungry and exhausted as well.
