Crawford Hill, Nebraska
Crawford Hill is a helper district with an average 1.55% eastbound grade between Crawford, Nebraska, United States, at an elevation of , and Belmont, Nebraska at on the BNSF Railway Butte Subdivision. Crawford Hill climbs the Pine Ridge escarpment—formations of buttes and grassy dense sand hills lined with ponderosa pines. Manned helper engines based in Crawford are used to help 18,000-ton () loaded coal trains from Wyoming's Powder River Basin up the escarpment. History In 1888, the Chicago, Burlington and Quincy Railroad began building a line west from Alliance, Nebraska to Edgemont, South Dakota to compete with the Fremont, Elkhorn and Missouri Valley Railroad. The challenge came when conquering the Pine Ridge escarpment. Upon reaching Belmont, engineers determined the only means of success would be constructing the Belmont Tunnel through the east face of the escarpment, with a steep grade and tight curves down into the settlement known as Crawford. In September 1889, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dakota, Minnesota And Eastern Railroad
The Dakota, Minnesota and Eastern Railroad is a wholly owned U.S. subsidiary of the Canadian Pacific Railway. Before its purchase, it was the largest Class II railroad in the United States, operating across South Dakota and southern Minnesota in the Northern Plains of the United States. Portions of the railroad also extended into Wyoming, Nebraska, Iowa, and Illinois. It interchanged with all seven U.S. Class I railroads. The DM&E began operations on September 5, 1986, over trackage spun off from the Chicago and North Western Transportation Company in South Dakota and Minnesota. The DM&E purchased the assets of I&M Rail Link railroad in 2002, renaming it Iowa, Chicago and Eastern Railroad. DM&E combined its management and dispatching duties with those of ICE under the holding company Cedar American Rail Holdings. The combined system connected Chicago through Iowa to Kansas City, Minneapolis-St. Paul and continued west to Rapid City, South Dakota. Smaller branches extended i ...

Boeing 787 Dreamliner
The Boeing 787 Dreamliner is an American wide-body jet airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 was rolled out without major operating systems, and then the aircraft experienced multiple delays until its maiden flight on December 15, 2009. Type certification was received in August 2011 and the first 787-8 was delivered in September 2011 before entering commercial service on October 26, 2011, with ANA. At launch, Boeing targeted the 787 with 20% less fuel burn than replaced aircraft like the Boeing 767, carrying 200 to 300 passengers on point-to-point routes up to , a shift from hub-and-spoke travel.

Hydraulic Fracturing
Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in 1947, and the first commercially successful application followed in 1950. As of 2012, 2.5 million "frac jobs" had been performed worldwide on oil and gas wells, over one million of those within the U.S. Such treatment is generally necessary to achieve adequate flow rates in shale gas, tight ga ...

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 ...

Distributed Power
In rail transport, distributed power (DP) is a generic term referring to the physical distribution—at intermediate points throughout the length of a train—of separate motive power groups. Such "groups" may be single units or multiple consists, and are remotely controlled from the leading locomotive. The practice allows locomotives to be placed anywhere within the length of a train when standard multiple-unit (MU) operation is impossible or impractical. DP can be achieved by wireless (RF connectivity) or wired (trainlined) means. Wired systems now provided by various suppliers use the cabling already extant throughout a train equipped with electronically controlled pneumatic brakes (ECP). History Since the 1960s, railroad distributed power technology has been dominated by one company, Harris Controls (originally Harris Corporation — Controls & Composition Division, later purchased by General Electric—the division now known as GE Transportation) who have manufactured and m ...

Horseshoe Curve
A horseshoe curve is a class of climbing curve in a roadbed which reverses turn direction (inflection) twice on either side of a single tight curve that varies through an angle of about 180 degrees or more. Such curves are more commonly found in a railway line but are also used in roads. The characteristic U shape, or even slight balloon shape, of such a curve resembles a horseshoe. On roadways, particularly tight versions of such curves are typically called hairpin turns. Theory A horseshoe curve is a means to lengthen an ascending or descending grade and thereby reduce the maximum gradient. Grade or gradient is defined as the rise divided by the run (length) or distance, so in principle such curves add to length for the same altitude gain, just as would a climbing spiral around one or more peaks, or a climbing traverse (cutting) wrapping around an end of a ridge. If the straight route between two points is too steep to climb, a more circuitous route will increase the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
