"Yesterday, I showed the Helen McGraw Tatem film, which is a VHS copy of C&S NG operations from the years, 1934-1937 it was interesting to see these films (the only ones I know of) of C&S NG operations. Ms. Tatem lived in Bailey and shot MP film of fascinating C&S NG operations in the final years. Incredible images, albeit not perfect."
Richard Jackson shot movies of the C&S. He captured #70 on the Clear Creek Line and some final action on the South Park. These sold as 8mm film by Al Chione in the 1970's and were made into VHS by WB Productions several years ago.
Engines featured: 70, 65 & 8 (Clear Creek line), 73, 69, 71, 8, 74 on the South Park.
I also have a Sunday River Production Film of the South Park.
