Starting in 1941, more than 50,000 Jewish Berliners were deported from Gleis 17 (platform 17) next to the S-Bahn station Grunewald. Some 186 trains left for Theresienstadt, Riga, Lodz and Auschwitz, carrying their Jewish cargo like cattle to the slaughter. Along the platform's edge, plaques record the departure dates, the number of people transported and the destination of each train. It’s quiet here, with only the trees rustling in the breeze, but the silence speaks loudly.
