Dusse-Alin Tunnel
The 378th longest tunnel in the world
The Dusse-Alin Tunnel is a two-kilometre-long railway tunnel on the Baikal–Amur Mainline (BAM) in Siberia, 88 kilometres east of Novy Urgal. Although it is named after the Dusse-Alin located about 150 kilometres (93 mi) further northeast, the line crosses the Bureya Range to enter the Amgun River valley just north of the Badzhal Range.
