Maybe I should have said inside the pre-war Germany borders, but even the resistance around Auschwitz wasn't doing hard sabotage missions, they were primary working in intelligence. The terrain was unsuitable for partisan warfare. The population was only partially supportive as many German and nationally indifferent people lived there. The local Gestapo was doing good work in destroying the underground resistance.
The cultivated forests around Auschwitz weren't much useful too.
A daylight attack on a train would be suicidal, especially around Auschwitz because of the dense rail and road networks there. A night attack would be slightly less suicidal but still an impossibility especially in 1942.
So lets see, the village and the territory around it were German and deep inside Germany proper. Kraków was always Polish - Koppitz never.
There were no railway line there, and it wasn't on the road to Auschwitz anyway. The Jews could escape from the train but had nowhere to go, the attack on the train was impossible. No to mention that the story portrayed in the film never happened.
Lots of avoidable inconsistencies - but fortunately there is always an easy solution to every problem, the producers should build a railway line to Kopice now, and the people living there today will gladly forgive the misuse of their village's name.
No to mention the people and their children who lived there then...
