On April 23, 1945, near the small village of Tröbitz (Lausitz), soldiers of the Red Army liberated more than 2300 completely debilitated and sick Jews, children, women and men. They had been deported as hostages from Bergen-Belsen concentration camp in a freight train known as the Lost Transport.

About 500 Jews died during the journey or in the days and weeks afterward. They were buried in mass graves along the train route and in Tröbitz. The traveling exhibition, which will also be shown in other stops along the train route after its opening, presents the life stories of eight children of the "Lost Transport" through photographs, drawings and texts.
