There are quite a few, Dave. For the later years of the C&S narrow gauge,
C&S ng by Mallory Hope Ferrell, (c) 1981 (p) Pruett Publishing Co.
ISBN 0-87108-534-8 (Mr. Ferrell posts here on NGDF from time to time and has written many excellent books on a variety of different railroads)
C&S High Line Memories and then some By Tom and Denise Klinger (c)2004 (p) Tom Klinger, ISBN 0-97612288-0-2 (The Klingers have published a companion book to this one which covers the C&S east to Denver)
If you can find a copy of any ofthe three books on the Denver, South Park and Pacific by Mac Poor et al which were published by the Rocky Mountain Railroad Club, you will find them to be "must have" books. All three are out of print and will be likely quite pricey. No mine are not for sale.
Hope this helps.
