I was pondering this question today while watching the national news stories on the blizzard hitting the northeast. This part of the country has many people who rely on commuter trains and if ten inches of snow falls on streets and highways, well the same amount falls on the metro lines. I've never seen a news report on if or how the tracks are cleared.
Here is a video of snow being cleared off tracks in Nebraska. I mean this is crazy cool. There's a plow type thing on the front of the engine which pushes the snow up and out a blower. Do they do the same for commuter lines?
I just didn't know. But now I do know. Here's a story out of New York City which uses what they call a snowjet. Same principal as out in Nebraska but the snow thrower looks a bit different.
I'm surprised we don't hear about these amazing things on the news during snow storms.
