Besides the Rio Grande's famed narrow-gauge lines two other future ventures would earn the railroad legendary status. At the Continental Divide northwest of Denver, the Denver and Rio Grande Western completed the famous Moffat Tunnel in 1928, some 6.1-miles in length and bypassing the torturous Rollins Pass, over 11,000 feet in height! The new tunnel cut down transit times over that section of main line from several hours to mere minutes and further strengthened the line's demand as a high-speed connection over the Rockies.
Even more famous than the tunnel was the introduction of a joint passenger train by the Burlington, Rio Grande, and Western Pacific in 1949 known as the California Zephyr deliberately routed through the mountains so that passengers could witness the stunning beauty offered over the Rio Grande's main line through the Rockies. Not surprisingly the train was an instant hit with the public and did so well that the Rio Grande elected not to include it in Amtrak in 1971 and would rename the train the Rio Grande Zephyr. The train by then was so well known that Amtrak did not hesitate to keep it in service when the Rio Grande finally did elect to relinquish the train in the early 1980s and even honored it by renaming it back to the California Zephyr in 1983.
Today, the Rio Grande and other classic fallen flag systems have been merged away into the Union Pacific and BNSF Railway which carry on much of what their predecessors left behind as many lines remain important routes. For a more in-depth look at Colorado's rail mileage over the years please refer to the table below. As you can see, during the height of rail travel Colorado was home to just over 5,500 miles of trackage. Today, that number has fallen to around 2,500 or a loss of 54%. Considering that many states have lost about half of their rail infrastructure since the 1920s Colorado's decline is fairly typical. Colorado also features a few smaller short line systems including the Great Western Railway of Colorado, Colorado & Wyoming Railway, Kyle Railroad, Nebraska, Kansas & Colorado Railway, Cimarron Valley Railroad, Denver Rock Island Railroad, Rock & Rail, San Luis Central Railroad, San Luis & Rio Grande Railroad, and the Towner Railway.
Along with the Durango & Silverton and C&T narrow-gauge operations the state boosts several other museums and tourist railroads. These include the Boulder County Railway Historical Society, Colorado Railroad Museum, Cripple Creek & Victor Narrow Gauge Railroad, Forney Museum of Transportation, Fort Collins Municipal Railway, Galloping Goose Historical Society, Georgetown Loop Historic Mining and Railroad Park, Leadville, Colorado & Southern Railroad, Mamtou & Pike's Peak Railway, Museum of Northwest Colorado, Platte Valley Trolley, Pueblo Railway Museum, Ridgway Railroad Museum, Royal Gorge Route Railroad, The Ski Train, and Windsor Museum.
Lastly, if you are planning a trip to Colorado to either railfan or enjoy the sites and sounds of the state's many museums and tourist railroads don't forget to stop by beautiful Denver Union Station in downtown Denver. It is well worth the drive to see! While it still serves Amtrak's California Zephyr and Southwest Chief, as well as the seasonal Ski Train, plans for the station's future include it becoming the city's hub of its ever-growing commuter rail system. In any event, the state's beauty alone is well worth a visit to the Centennial State, whether your interested in Colorado railroads or not! All in all there is plenty to do and see all across the state so you are bound to have a wonderful visit whatever you decide to do.
