In June 1941, just over three decades after the abandonment of the Alpine Tunnel, Railroad Magazine published an article titled "The Alpine Tunnel Route."
I posted the article here. The author, Lewis R. Lathrop, was a D&RG fireman who knew South Park trainmen who ran trains over the "hill" through the famous tunnel and swapped stories with them in a cigar store. In fact, he started work with the Rio Grande just two years after the arrival of the DSP&P into Gunnison.
There are some epic stories in here including one in which a crew of trainmen and snow shovelers managed to turn an engine around with hydraulic jacks. I admit, I still don't understand how they did it. Essentially, a snow blockade kept them from getting through the east portal of Alpine Tunnel, but snow had drifted back behind them. They decided they had a better chance at plowing through the line westward back to Pitkin, but...they needed to turn an engine around with a plow on the front.
While discussing some epic snowbucking skills the South Park railroaders possessed, Lathrop, the D&RG man, admitted that the DSP&P had superior equipment to theirs and that the DSP&P railroaders were better skilled at fighting snow. As evidence he tells of a blockade of Marshall Pass where two South Park "hoggers" opened the Rio Grande line themselves.
Lewis A. Lathrop actually, as the article puts it, "crossed the great divide" a few months before publication of this article. His son Gilbert assisted with its completion.
