Primarly it was planned to build 19 tunnels with total length 1793 meters on the Round Baikal Railway. But the breaking was complicated with relief and situation of tunnels on the curved sections. In fact 39 tunnels with the total length 8004 meters were built. While building tunnels they used as well hand-operated as electropneumatic and electric drilling.
