Phew, yes that will clear the snow all right. What a beauty.

Saw this on a friend's FB line, and have a friend who has actually seen this behemoth in action.
Essentially a giant rotary snow blower that's essentially a couple of steam engines harnessed to a giant fan that blows away any snow blocking the tracks on the White Pass & Yukon railway line in Skagway, Alaska.
Built in 1899, mothballed in 1964, brought back to use in the mid 90s and still in use. The results are spectacular as you can see in a couple of videos posted later in this thread. Here's a video of what it does - from a standing start to powering through a huge mound of snow piled up and blocking a railway line.

Looks like a Tunnel boring Machine on wheels! Quiet extreme!
Looks like it is used to clear the tracks when an avalanche buries the track in snow!
is there a video link to see it in action?
I wonder how much slippage there is for those steel wheels on the tracks, especially when they are cold, covered with snow, and facing the opposition of piles of snow that need to be cleared!

So true! Though there's a huge difference in scale:

Too big and heavy to fall? I guess the weight and forward momentum of that thing keep it going
