The Denver, Boulder & Western/Colorado & Northwestern Railroad, built from Boulder westward to the mining communities of Ward and Eldora, is seldom mentioned on this forum. It is not well known that the C&N not only had a Shay (which ended up on the Silverton), but it also had (briefly) a Climax. The Climax was the first 3-trucker the factory in Corry, PA, built. For reasons unclear to me, it is was not successful on the C&N (too slow for the distances that had to be traveled?) and it quickly left the property, ending its life on the WP&Y. Here are some pics of the locomotive on the C&N.
