The Broadmoor Pikes Peak Cog Railway (also known as the Pikes Peak Cog Railway and Manitou and Pike's Peak Railway) is an Abt rack system cog railway with 4 ft 8 1⁄2 in standard gauge track in Colorado, climbing the well-known mountain Pikes Peak. The base station is in Manitou Springs, Colorado near Colorado Springs. The railway is the highest in North America by a considerable margin. It was built and operated solely for the tourist trade. Pikes Peak is the highest summit of the southern Front Range of the Rocky Mountains, in North America. The ultra-prominent 14,115-foot fourteener is located in Pike National Forest, 12 miles west of downtown Colorado Springs, Colorado. The summit is higher than any point in the United States east of its longitude.— Wikipedia
The Durango & Silverton Narrow Gauge Railroad (D&SNG) is a 3 ft narrow-gauge heritage railroad that operates 45.2 miles of track between Durango and Silverton, in the state of Colorado. The railway is a federally designated National Historic Landmark and is also designated by the American Society of Civil Engineers as a Historic Civil Engineering Landmark. The route was originally opened in 1882 by the Denver & Rio Grande Railway (D&RG) to transport silver and gold ore mined from the San Juan Mountains. The line from Durango to Silverton has run continuously since 1881, although it is now a tourist and heritage line hauling passengers, and is one of the few places in the U.S. which has seen continuous use of steam locomotives.— Wikipedia
