IMHO, the most compact and "modelegenic" ice facility in Platte Canon was Haviland (MP 45.1), with its twin ice storage houses:
According to Poor, the ice houses were served by a 355 foot spur; the 1918 ICC valuation map shows the siding in place inside the curve, but the switch to the main being disconnected.
I've found no reference that ice harvested at Haviland was shipped to Denver. It may have been a harvesting and storage operation to provide ice to the various resorts between South Platte and Grant, during the summer vacation seasons.
I agree with Rick. The photos in the Klingers' book show two locomotives handling a long string of boxcars at Maddox, with no indication they will then proceed west bound. The C&S number 9 black and white film footage shows ice harvesting and loading at Maddox. The string of empty box cars are periodically re-spotted at the loading platforms by the use of a Ford model-A truck, pushing at one corner of a box car. So each ice harvest may have required two extras out of Denver, first to deliver a long string of empties for loading, a second to retrieve the loaded cars of ice, to haul them back to the Denver ice houses.
And yes, the locomotives were likely backed down to Pine (less than 3 miles), where they were turned on the wye, before hauling the train on down to Denver.
