Track switches, derailment. Snow and wind as a combination are the hardest condition for track switches, which are the moving track parts meant for directing the train to the right track. Wind causes snow to move horizontally, packing it between switches moving part and preventing its movement. Packed snow can prevent switch movement, or lodge it halfway between positions, creating a possible derailment of the train.
