Reversal about the end

Regarding the final reversal of the film, there are two possibilities:

First, because of his homeland being destroyed, his race was slaughtered by the Nazis, and he had mental problems, he imagined that his village had escaped the disaster by building a train, but in fact none of these things ever existed.

Second, Schlammer's village made one such migration, but was taken back to Auschwitz by the time they reached the border.

Personally, I am more inclined to the first explanation. In the context of the turmoil at that time, countless people were displaced and their homes were destroyed. The consequences of these disasters are undoubtedly various. This kind of beautiful fantasy before death is like the fantasy of a little girl selling matches.

The film itself is very interesting and can be compared with "Life is Beautiful".
