Circum-Baikal railway lies on a narrow coastal strip of Lake Baikal. To accommodate railroad in rocks hewn shelves everywhere. Put retaining walls to expand and strengthen the road. Cut a tunnel through the headlands and cliffs, to build bridges and viaducts over rivers and bays of Lake Baikal. Many rivers and streams because of their steep temper had put a stone gutters, pipes and trays. Strengthened even rocks. Judge for yourself. Builders have erected 41 tunnel. 40 of them survived. The total length of the tunnels for about nine and a half miles. It was built 15 stone galleries and 3 of concrete. Through rivers, streams, paddy, hollows, coves of Lake Baikal was airlifted about 470 large and small bridges, viaducts and 6. To protect the road was built about 270 different fortification: retaining walls, paving, and others. It was built in 1918 of stone pipes and trays. By some estimates, for every 100 meters of the way to Baikal railway engineering, there is one technical construction. Impressive? All this needs to be seen with my own eyes.
