Single-track wedge snowplows were already in use in the 1940s. They still do not go out of fashion due to their functionality and reliability... They are used when the depth of the snow cover does not exceed 60 cm... During snow removal, the system throws snow on both sides of the train, creating huge snowdrifts right next to the railway tracks. #ToInteresting Welcome, anyone who wants to support our channel can become a sponsor! / @tointeresujace7074
