The new tunnel is to increase the traffic capacity of the Baikal-Amur Railway Line. The trains have been running in both directions so far through the old single-track Baikal tunnel that was commissioned on December 31, 1985. Before the old tunnel had been built, the trains ran along a temporary detour line that was 16.2 kilometers long. The detour line had quite a few temporary installations including bridges and viaducts that were 30 to 35 meters high in some locations.
