Tunnel opens on Novokuznetsk avoiding line – Railway Gazette
The 1 158 m long Tomusinksy tunnel now has a second bore, alleviating a bottleneck near Novokuznetsk.
RUSSIA: Completed by Russian Railways at a cost of 7bn roubles, a second bore of the 1 158 m long Tomusinksy tunnel north of Novokuznetsk opened for revenue service on October 3.
The second bore alleviates a significant bottleneck formed by the original single-track tunnel, opened in 1967. This forms part of an avoiding line used largely by heavy freight trains to bypass central Novokuznetsk, which lies on a strategic coal corridor linking the Kuzbass mining region with Mezhdurechensk.
Construction of the second tunnel began in September 2012 with commissioning and test running starting in September 2017. Tunnel opens on Novokuznetsk avoiding line – Railway Gazette
