Cerro Summit
Cerro Summit (elevation ) is a mountain pass in the State of Colorado, located about 14 miles east of Montrose, Colorado. It divides the watershed of the Cimmaron River to the east and the Uncompahgre River to the west, both of which eventually flow into the Gunnison River. The summit is traversed by U.S. Route 50. Until 1949, Cerro Summit was part of the Denver and Rio Grande Western Railroad's Black Canyon line which ran between Gunnison and Montrose. When constructed in 1882, the route was originally part of the D&RGW's transcontinental line to Salt Lake City and remained so until more direct routes were built in the early 20th century. Although grades on U.S. 50 are gentle, the former rail line over Cerro Summit had a ruling gradient of 4% or 1 in 25 and it was not uncommon for most freight trains to require a banker A bank is a financial institution that accepts Deposit account, deposits from the public and creates a demand deposit while simultaneously making lo ...

Gunnison, Colorado
Gunnison is a home rule municipality that is the county seat and the most populous municipality of Gunnison County, Colorado. The city population was 6,560 at the 2020 United States Census. Gunnison was named in honor of John W. Gunnison, a United States Army officer who surveyed for a transcontinental railroad in 1853. History The City of Gunnison got its name from the first known European-American explorer of the area, John W. Gunnison. He was searching for a route for the transcontinental railroad in 1853 and only stayed for three days before traveling west to Utah. Gunnison saw its first population increase in the 1870s, due to the mining surge throughout the state. The railroad arrived soon after in 1880 to appreciative miners, ranchers, and farmers. In the early 1800s, the groups moving into the Gunnison area were mainly fur trappers and mountain men, trying to make a living for themselves in the rocky mountain terrain. But a drop in fur prices in the 1840s essentially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Space Reserve
An open space reserve (also called open space preserve, open space reservation, and green space) is an area of protected or conserved land or water on which development is indefinitely set aside. The purpose of an open space reserve may include the preservation or conservation of a community or region's rural natural or historic character; the conservation or preservation of a land or water area for the sake of recreational, ecological, environmental, aesthetic, or agricultural interests; or the management of a community or region's growth in terms of development, industry, or natural resources extraction. Open space reserves may be urban, suburban, or rural; they may be actual designated areas of land or water, or they may be zoning districts or overlays where development is limited or controlled to create undeveloped areas of land or water within a community or region. They may be publicly owned or owned by non-profit or private interests. A certain amount of overlap occurs w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bank Engine
A bank engine (United Kingdom/Australia) (colloquially a banker), banking engine, helper engine or pusher engine (North America) is a railway locomotive that temporarily assists a train that requires additional power or traction to climb a gradient (or ''bank''). Helpers/bankers are most commonly found in mountain divisions (called "helper districts" in the United States), where the ruling grade may demand the use of substantially greater motive power than that required for other grades within the division. Historic practice Helpers/bankers were most widely used during the age of steam, especially in the American West, where significant grades are common and trains are long. The development of advanced braking systems and diesel-electric or electric locomotives has eliminated the everyday need for bankers/helpers in all but a few locations. With the advent of dynamic brakes on electric or diesel-electric locomotives, helpers/bankers can also be used to provide more braking fo ...

Ruling Gradient
The term ruling grade is usually used as a synonym for "steepest climb" between two points on a railroad. More simply, the steepest grade to be climbed dictates how powerful the motive power (or how light the train) must be in order for the run to be made without assistance. Even if 99% of the line could be run with a low-powered (and inexpensive) locomotive, if at some point on the line there is a steeper gradient than such train would be able to climb, this gradient "rules" that a more powerful locomotive must be used, in spite of it being far too powerful for the rest of the line. This is why special "helper engines" (also dubbed "Bankers") are often stationed near steep grades on otherwise mild tracks. It is cheaper than running a too-powerful locomotive over the entire track mileage just in order to make the grade, especially when multiple trains run over the line each day (to help justify the fixed daily cost of the helper operation). In the 1953 edition of ''Railway Engineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of inc ...

Transcontinental Line
A transcontinental railroad or transcontinental railway is contiguous railroad trackage, that crosses a continental land mass and has terminals at different oceans or continental borders. Such networks can be via the tracks of either a single railroad or over those owned or controlled by multiple railway companies along a continuous route. Although Europe is crisscrossed by railways, the railroads within Europe are usually not considered transcontinental, with the possible exception of the historic Orient Express. Transcontinental railroads helped open up unpopulated interior regions of continents to exploration and settlement that would not otherwise have been feasible. In many cases they also formed the backbones of cross-country passenger and freight transportation networks. Many of them continue to have an important role in freight transportation and some like the Trans-Siberian Railway even have passenger trains going from one end to the other.

Denver And Rio Grande Western Railroad
The Denver & Rio Grande Western Railroad , often shortened to ''Rio Grande'', D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a narrow-gauge line running south from Denver, Colorado, in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic. The Rio Grande was the epitome of mountain railroading, with a motto of ''Through the Rockies, not around them'' and later ''Main line through the Rockies'', both referring to the Rocky Mountains. The D&RGW operated the highest mainline rail line in the United States, over the Tennessee Pass in Colorado, and the famed routes through the Moffat Tunnel and the Royal Gorge. At its height, in 1889, the D&RGW had the largest narrow-gauge railroad network in North America with of track interconnecting the states of Colorado, New Mexico, and Utah. Known for ...

Gunnison River
The Gunnison River is located in western Colorado, United States and is one of the largest tributaries of the Colorado River. Description The river flows east to west and has a drainage area of according to the USGS. The drainage basin of the Gunnison collects water from different habitats, such as forests and alpine meadows, located the along Continental Divide. As the river flows westward, it carves through the San Juan Mountains. It flows into the Colorado River at Grand Junction. The Gunnison River Basin is popular for recreational activities such as fishing, rafting, boating, camping, hiking, and rock climbing. Contamination of the Gunnison River with selenium and mercury results from irrigation of high-selenium soils derived from the Mancos Shale and from mineral mining. The region surrounding the Gunnison River is part of the Colorado Mineral Belt. Contamination of the Gunnison River with selenium and mercury is a conservation concern for the bonytail chub, Colora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
