Great photos, Todd!
December 4th, 1913, was the day of the great blizzard that paralyzed the Denver area, including Clear Creek and Platte Canyon.
According to the Klingers'
C&S Platte Canyon Memories . . . , C&S 9 and 70 were double heading the first westbound passenger train out of Denver on December 8th and made it as far as Maddox.
There is a companion photo in the book to complete your three images:
Looks like the derailment occurred at the switch to the siding at Maddox.
Note the tool box above the firebox door of number 70.
