Your map is definitely a work in progress. I will not drive you into the ground about it. But if you are going to map the railroads of Colorado both operating and abandoned, please take the time to research were they were located. I have uncovered numerous discrepancies in your work in just a little segment of your map in Southwest Colorado. It looks like you just put lines down marking a general area where the railroad was or is, (don't get me wrong its great for rough locating of a railroad). But you should focus more on the quality of mapping the railroads such as focusing on the actual locations of past and current locations of railroads, the grades, and curvature, your curves look like squared off circles, make your curves flow and more appealing to look at. I specialize in mapping the former railroads of Southwest Colorado, focusing on the lumbering, mining railroads of the San Juan extension of the Denver & Rio Grande from Chama to Durango including the Pagosa Springs branch. I spent almost a year working on mapping the former railroads with a great informative friend and colleague who has been out there in person mapping and pin pointing the exact routes of the railroads. It takes time to present quality work. I am amazed with how much you covered in a few years. You have done well, but now its time to go back and clean it all up and put it in its proper place. Personally I will only use it to roughly point out where railroads were located and thats it. I would love to show samples of my work but its copy righted and my partners and I do not want it published as of yet.
I do not want to start a flame war and this is where it ends. It is just constructive criticism, take it however you want to. Best of luck with your mapping!
We have witnessed valley
and plain and crest,
Canon and pass we've scanned;
We have seen the best
of the glorious West,
by the trail of the Rio Grande
