Snow Removal on Railway Transport: Strategy for Protecting Steel Railways Ensuring uninterrupted train movement during the winter period is a complex logistical and engineering task. Unlike road infrastructure, railway infrastructure is vulnerable not only to snow on the track but also to icing of the contact network, snowdrifts in cuttings, the formation of snow dunes on stretches, and avalanche danger. The fight against snow here is proactive, combining powerful specialized equipment, continuous monitoring, and clear protocols of action. Primary Threats and Strategies for Combating Them Track snowdrifts and the formation of snow drifts. Threat: Snow blown by the wind can completely block the track, posing a risk of train derailment, damage to running gear, and blocking of movement. Equipment and methods: Snowplows: There are ram (light, for fresh snow), rotary (heavy, for compacted drifts), and auger-rotary (most powerful). Rotary snowplows (such as Soviet SM-2 or modern PSS-1M) are the "kings" of clearance. Their augers grind the snow, and the rotor throws it 20-50 meters away from the track. Plow snowplows: Installed on locomotives or special wagons for clearing tracks of fresh snow of low height. Interesting fact: In the extreme north (Yakutia, the Kola Peninsula), permanent snow protection screens and galleries — a kind of "tunnels" through which the railway passes — are built at the design stage to protect tracks from snow drifts. Icing of switch points and the contact network. Threat: Ice blocks the mechanism of switch points, disrupting routing. Icing of the contact wire leads to a loss of contact with the collector, sparking, and breaks. Equipment and methods: Switch heaters: Gas (propane-butane) or electric systems built directly into the switch structure. They are activated automatically by temperature and humidity sensors. Train defectoscopes and snowplows with special equipment: Modern diagnostic complexes (in Russia — PDK/PDM) combine the functions of ... Read more
