The Moffat Road extends from Denver, Colorado, westward into the Front Range of the Rocky Mountains.  This former Denver and Rio Grande Western line is now under the ownership of the Union Pacific Railroad.   This is one of the most rugged mountian rail lines in the world and a favorite site for many railfans, myself included.  This is the modest beginning of my set of pages dedicated to this historic mileage of track which includes the famous Tunnel District and the 6.21 mile long Moffat Tunnel.  These pages will contain trackside images of the route.  For images of the Moffat Road taken from the rails, please visit the companion pages to this set, my Rio Grande Ski Train Excursion Pages.  Enjoy your visit... -Jason

UP-001-BigTen-s.jpg (15013 bytes) August 29, 1998 This is the S curve as know as the "Big Ten" and "Little Ten" Curves, or many times as simply the "Big Ten" Curves.   It is so named because of it's tight 10 degree radius of curvature.  Visible in this picture are a string of hopper cars filled with dirt and permanently placed on the inside of the curve to act as a wind break.  Note:  A ten degree curve means that the centerline of the rails curves at a radius such that it is 10 feet off of a line tangent to the curve at 100 feet.
