I agree with you Festus about the reality being that we need to support the railways that already exist. However, just for fun, I too have rebuilt in my mind the old CC&CS line from the springs to Cripple Creek. The problem I kept running into is where to place the new tracks once you are almost down the hill heading for the Springs?
As you know, the narrow grade of the CC&CS turns into a paved road and subdivisions. So what could you come up with for a western terminal for the rebuilt CC&CS??
Just for fun.
