In my post, Trains in Snow: Faith Required, I'm showing how train engineers lose sight of the tracks while plowing across snow-covered rails. The video of the train going over a bridge with virgin snow all around is especially nerve-wracking.
I've also included a video of a Romanian train clearing tracks with a rotary snow blower in action and although it's not on the video, the train derailed twice while affecting this task.
And if you think the image above is something that only happens in the olden days, I've posted a Parks Canada photo taken at Glacier National Park.
Now that's more snow that I EVER want to shovel.
