I don't think trains de-ice anything, no one's out there deicing train tracks - they are far too remote

    Here in Canada there are definitely de-icing/ snow removal machines used on the tracks. Large propane heaters keep switches clear of ice so they can operate. Hi-rail trucks will go ahead of trains through the mountain passes to ensure the way is clear. During particularly bad snow storms they can use machines like this to clear the snow.

    The trains will also release gravel on the rail to improve braking times.
