Fritz; A quick and not really thorough look at some of my slides makes me believe your picture is from a Rocky Club trip, 1962, I believe. The consist, with the baggage car in the middle where it served as a commissary, and with the 476 as power, if my memory is correct it was the only time the 476 was used when I was on one of the trips. I liked that little engine and was dissappointed when we got other engines.
If I get a little time I will check to see what engines we doubled with leaving Alamosa, up to Silverton and then out of Chama going up Cumbres.
