mg: aww, Matthew just beat me to it. Good Job :thumbs_up: "In 1887 the C., B. & Q. purchased the securities of the Denver, Utah & Pacific railroad company, a narrow gauge road from Denver to Lyons, Colorado, with two short branches, aggregating about 49 miles of road, which had been built from 1881 to 1885. It was, however, operated independently and was not included in the mileage of the C., B. & Q. until 1889, when it was changed to standard gauge."
Maybe that clue was too good of a clue.... You are correct. The DU&P had done some grading into what is now South Boulder Canyon, but never laid track into SBC. David Moffat and his Denver, Northwestern & Pacific built high ont he canyon wall above the DU&P mainline. Much of the DU&P still exists as sturdy rockwork, and grading.. Great job! Next!
Last common-carrier narrow-gauge railroad to be built in the U.S. First incorporated in 1914, reincorporated under a different name in 1917. Locomotives acquired secondhand from the Florence and Cripple Creek Railroad, recently abandoned. Ran west from a connection with the Oregon Short Line in Divide. Abandoned in 1941. Try it. :teeth:
Google helps alot.:teeth: Organized in 1903 as an interurban railroad, this line failed to connect the 3 city's that form its name. It survives today as a class 3 switching railroad consisting of two seperate yards. Major customers are a gravel pit, cement industry, and two large grain elevators.
Yule Tram, near Marble CO. Fourteen percent grade to marble quarries. Connected with Crystal River and San Juan Railroad...
oops, I should have said steepest grade of any line haul railroad in the U.S. I think the grade is still used today by a port authority of the namesake town.
