Trains to extermination camps Departing from Westerbork, 93 severely overcrowded trains depart for a secret 'labor camp' situated somewhere in the eastern region. Typically, these trains followed a path through Assen, Groningen, Nieuweschans, Bremen, Wittenberg, to Berlin-Spandau. From there, the transports continued through to Breslau, then to Czestochowa, ultimately turning south and ending at Auschwitz.
