You recall Jim McKee's Cumbres posting for this date indicating the rotary OY and train 116 became snowbound at Los Pinos and my subsequent postings of clearing the line/rescue operations.
I recommend taking a look at Mr. Dorman's "Chama/Cumbres With A Little Chili", pages 92 and 93. There you will find an account by a passenger on the snowbound train 116.
