Studies of geologist A.V. Lvov on the Circum-Baikal railroad

The article deals with the activities of geologist A.V. Lvov during the survey work of the Circum-Baikal railroad and at the beginning of operation of the Transbaikal railroad. A detailed survey of the outcrops formed during the construction of the railroad made it possible to refute the previously proposed conclusions of mining engineers and to give detailed recommendations on the protection of the railroad bed from rockfalls, both during construction and at the beginning of the operation of the railroad. Along with geological studies, work was done to determine the sources of water inflow into the most problematic tunnel on the railroad.
