The uncompleted railway across Northern Siberia was one of the most shameful projects of the post-war era, involving many deaths and huge discomforts. Hailed by Stalin himself as a major part of his 'Great Plan for the Transformation of Nature', the scheme was dropped at his death in 1953. By that time, less than 600 kilometres were in working operation, even though up to 300,000 persons had been involved and about a third of them had perished, while more than 40 billion rubles of capital investment had been wasted. Ghostly labour camps, rusting rolling stock and rails, hundreds of bridges remain in what has been called 'an open air museum of human technology', preserved by nature's refrigerator - the tundra. The article describes the reasons for the railway project and the 'Great Plan', the organization involved, and the conditions in which the enslaved workforce struggled for survival and died.
