I looked through the archive of the Rocky Mountain Rail Report, the newsletter of the Rocky Mountain Railroad Club and put
a post together with some miscellaneous South Park Line/C&Sng news from the 1960-1961 editions including:
The break-even point and final sales of the Pictorial Supplement to the DSP&P book by E.J. Haley, Richard Kindig, and M.C. Poor
Information on the operation of the now-standard gauged C&S Climax to Leadville line, including C&S rotary 99201.
Lists of C&S/CB&Q steam engines recently scrapped, the few left in the scrap line, and a list of engines on display, including the narrow gauge ones (Numbers 9, 60, and 71)
Information on a 1961 renovation of C&S caboose 1006 in Silver Plume.
Enjoy,
Kurt
1006 in Silver Plume, 1960s (1961 or later, after she was finally put on rails)
