Snow has been a plague of biblical proportions here in Newfoundland when we had a railway. It was cheaper to cut through an area called the Gaff Topsails but the price was dealing with the snow.
A much better description than I could ever write can be found at this link. I would suspect that quite a few areas in Canada suffered from similar conditions.
Thought I had seen this picture of the Nickel Plate Road and the 58 Chev before...found it way back on page 30 #596 to be exact but it was not the same one as it turns out. Guess the guys at NPR liked 58 Chevrolets...
