The construction of the Baikal-Amur Mainline (BAM) in East Siberia and the Russian Far East in the 1970s and 1980s was the largest technological and social engineering project of late socialism. After the dissolution of the Soviet Union, the BAM was dogged by economic bust, decline, and public disillusionment. BAM-2, a recently launched state program of technological modernization, aims to complete a second railway track. The project elicits memories as well as new hopes and expectations, especially among “builders of the BAM.” This article explores continuity and change between BAM-1 and BAM-2. It argues that the reconstruction efforts of the postsocialist state are predetermined by the durability of the infrastructure as a materialization of collective identities, memories, and emotions.
