Trekker Zay Harding boards the infamous “Ice Train” for a wintry trip to the far north of Siberia, deep inside the Arctic Circle on the world’s northernmost railway line. His journey takes him through Tobolksk to the gas fields of Novy Urengoy and follows the abandoned route of Stalin’s “Railway of Death.” He visits a Communist gulag and camps overnight with the Nenet nomadic tribe.
