Chełmno extermination camp
During the most deadly phase of the Holocaust in Poland on January 16, 1942, the "SS" and police began deportations from the Łódź Ghetto to the Chełmno extermination camp nearby. German officials transported the Jews from Łódź by train to Koło railway station, six miles (10 km) northwest of Chełmno. There, the "SS" and police personnel supervised transfer of the Jews from the freight as well as passenger trains, to smaller-size cargo trains running on a narrow-gauge track, which took them from Koło to the Powiercie station.
