I suggest that you part with a few dollars, and buy one or more of the books on Cripple Creek railroads.
First, the oldest and the only one to treat all of the railroads is Morris Cafky's "Rails Around Gold Hill". It won't come cheap but it covers all 3 railroads and the electric lines
There are a pair of Colorado Rail Annuals from the Colorado Railroad Museum, one on the F&CC (#13) and one on the CS&CCD (#16). Both are by Tivis Wilkins.
There is Mal Farrell's book on the Midland Terminal "The Cripple Creek Road" which has much more material than Cafky's because it is later.
There is also a second book on the F&CC, "Forty Miles to Fortune" by Allen Lewis
If you cannot find the answers to your questions in these books, there is not a whole lot that they don't cover.
