Relative Train Length and the Infrastructure Required to Mitigate Delays from Operating Combinations of Normal and Over-Length F

IMechE 2018 Article reuse guidelines: infrastructure required to mitigate sagepub.com/journals-permissions DOI: 10.1177/0954409718809204 delays from operating combinations journals.sagepub.com/home/pif of normal and over-length freight trains on single-track railway lines in North America C Tyler Dick , Ivan Atanassov, F Bradford Kippen III and Darkhan Mussanov Abstract Distributed power locomotives have facilitated longer heavy-haul freight trains that improve the efficiency of railway operations. In North America, where the majority of mainlines are single track, the potential operational and economic advantages of long trains are limited by the inadequate length of many existing passing sidings (passing loops). To alleviate the challenge of operating trains that exceed the length of passing sidings, railways preserve the mainline capacity by extending passing sidings. However, industry practitioners rarely optimize the extent of infrastructure investment for the volume of over-length train traffic on a particular route. This paper investigates how different combinations of normal and over-length trains, and their relative lengths, relate to the number of siding extensions necessary to mitigate the delay performance of over-length train operation on a single-track rail corridor. The experiments used Rail Traffic Controller simulation software to determine train delay for various combinations of short and long train lengths under different directional distributions of a given daily railcar throughput volume. Simulation results suggest a relationship between the ratio of train lengths and the infrastructure expansion required to eliminate the delay introduced by operating over- length trains on the initial route. -

Transcontinental Railroad Fact Sheet
Transcontinental Railroad Fact Sheet Prior to the opening of the transcontinental railroad, it took four to six months to travel 2000 miles from the Missouri River to California by wagon. January 1863 – Central Pacific Railroad breaks ground on its portion of the railroad at Sacramento, California; the first rail is laid in October 1863. December 1863 – Union Pacific Railroad breaks ground on its portion of the railroad in Omaha, Nebraska; due to the Civil War, the first rail is not laid until July 1865. April 1868 – the Union Pacific reaches its highest altitude 8,242 feet above sea level at Sherman Pass, Wyoming. April 28, 1869 – a record of 10 miles of track were laid in a single day by the Central Pacific crews. May 10, 1869 – the last rail is laid in the Golden Spike Ceremony at Promontory Point, Utah. Total miles of track laid 1,776: 690 miles by the Central Pacific and 1086 by the Union Pacific. The Central Pacific Railroad blasted a total of 15 tunnels through the Sierra Nevada Mountains. It took Chinese workers on the Central Pacific fifteen months to drill and blast through 1,659 ft of rock to complete the Summit Tunnel at Donner Pass in Sierra Nevada Mountains. Summit Tunnel is the highest point on the Central Pacific track. The Central Pacific built 40 miles of snow sheds to keep blizzards from blocking the tracks. To meet their manpower needs, both railroads employed immigrants to lay the track and blast the tunnels. The Central Pacific hired more than 13,000 Chinese laborers and Union Pacific employed 8,000 Irish, German, and Italian laborers. -
The Influence of Hydrology and Climate on the Isotope Geochemistry
Sedimentology (2007) doi: 10.1111/j.1365-3091.2007.00932.x The influence of hydrology and climate on the isotope geochemistry of playa carbonates: a study from Pilot Valley, NV, USA CYNTHIA M. LIUTKUS* and JAMES D. WRIGHT *Department of Geology, Appalachian State University, ASU Box 32067, Boone, NC 28608, USA (E-mail: [email protected]) Department of Geological Sciences, Rutgers University, 610 Taylor Road, Piscataway, NJ 08854, USA ABSTRACT Carbonates often accompany lake and lake-margin deposits in both modern and ancient geological settings. If these carbonates are formed in standing water, their stable isotope values reflect the aquatic chemistry at the time of precipitation and may provide a proxy for determining regional hydrologic conditions. Carbonate rhizoliths and water samples were collected from a playa lake in eastern Nevada. Pilot Valley (43°N) is a closed-basin, remnant playa from the Quaternary desiccation of palaeo-Lake Bonneville. Water is added to the playa margin by free convection of dense brines to the east and forced convection of freshwater off the alluvial fan to the west. Both freshwater and saline springs dot the playa margin at the base of an alluvial fan. Water samples collected from seven springs show a range from )16 to )0Æ2& (Vienna Standard Mean Ocean Water), and are consistent with published values. The 18 ) ) d Ocalcite values from rhizolith samples range from 18Æ3to 6Æ7& (Vienna Pee Dee Belemnite), and the average is )12& V-PDB (1 ) r SD 2&). With the 18 exception of samples from Little Salt Spring, the range in the d Ocalcite values collected from the rhizoliths confirms that they form in equilibrium with ambient water conditions on the playa. -

Landscape Medallion in Washington State
Architect of the Capitol Landscape medallion (detail), Brumidi Corridors. Brumidi’s landscape medallions relate to the federally sponsored Pacific Railroad Report and depict scenes from the American West, such as this view of Mount Baker in Washington State. The “MostBrumidi’s Landscapes andPracticable the Transcontinental Railroad ”Route Amy Elizabeth Burton or 150 years, senators, dignitaries, and visitors to the U.S. Capitol have bustled past 8 Flandscape medallions prominently located in the reception area of the Brumidi Corridors on the first floor of the Senate wing. For most of this time, very little was understood about these scenes of rivers and mountains. The locations depicted in the landscapes and any relevance the paintings once held had long faded from memory. The art of the Capitol is deeply rooted in symbolism and themes that reflect national pride, which strongly suggested that the medallions’ significance extended beyond their decorative value. Ultimately, a breakthrough in scholarship identified the long-forgotten source of the eight landscapes and reconnected them to their his- torical context: a young nation exploring and uniting a vast continent, as well as a great national issue that was part of this American narrative—the first transcontinental railroad.

03-20-1869 Jupiter.Indd
This Day in History… March 20, 1869 First Run of McQueen’s Jupiter The Jupiter, also known as Central Pacific Railroad #60, made its first run on March 20, 1869. Less than two months later, the Jupiter made history as one of the two locomotives that met at Promontory Summit, Utah to mark the completion of America’s First Transcontinental Railroad. Jupiter was a popular name for locomotives in the 1800s. Named after the “King of Gods” or the “God of the Sky,” Jupiter was a name that inspired wonder and excitement. Walter McQueen designed his Jupiter, a 4-4-0 steam locomotive, and it was built in 1868 at the Schenectady Locomotive Works. Once complete, it was disassembled and transported by ship to the Central Pacific headquarters in For many years it was believed the San Francisco. Jupiter was reassembled and had its first run on March 20, 1869. Jupiter was red, but a newspaper It was run up and down a test track on Front Street and reportedly ran perfectly. article was discovered in the 1990s Jupiter was then sent to Nevada to haul passenger trains.

If we had a $ or £ or € for every time we’ve been asked how to wire track and point-work, we’d be writing this on a beach somewhere while sipping a cold beer! A great layout needs good trackwork, so first - a word about trackwork and getting good performance. Choose carefully! DO think about making your own turnouts if you have even moderate skills. It is not as hard as you think, needs only basic skills and tools... and we do our best to make it easy with our top quality gauges, trackwork frets and templates. PLUS we will soon provide a detailed “How to make track” tutorial too. Interested? Then call or email us and we will do our best to help you. No matter what scale you will model in, DO NOT even consider using insulated frogs! Yes, lazy retailers who do not understand what they sell - and modellers who have never done a proper job of laying track so it runs well may well recommend it to you… but do NOT be tempted. No matter which brand makes the turnouts, if you use insulated frogs, you WILL have small locos stalling or also suffer from wider wheels bridging the frog tip and creating momentary shorts that are hard to fix and really are a source of constant frustration. Use more realistic rail sizes please: Usually this will be code 55 in N, or Code 75 and 83 in OO or HO Scale. -

Race to Promontory
This resource, developed by the Union Pacific Railroad Museum, is a comprehensive guide for telling the story of the first American transcontinental railroad. In addition to bringing to life this important achievement in American history, this kit allows students to examine firsthand historical photographs from the Union Pacific collection. This rare collection provides a glimpse into the world of the 1860s and the construction of the nation’s first transcontinental railroad. Today, nearly everything American families and businesses depend on is still carried on trains – raw materials such as lumber and steel to construct homes and buildings; chemicals to fight fires and improve gas mileage; coal that generates more than half of our country’s electricity needs; produce and grain for America’s food supply; and even finished goods such as automobiles and TVs. After 150 years, UP now serves a global economy and more than 7,300 communities across 23 states.

Great Salt Lake FAQ June 2013 Natural History Museum of Utah
Great Salt Lake FAQ June 2013 Natural History Museum of Utah What is the origin of the Great Salt Lake? o After the Lake Bonneville flood, the Great Basin gradually became warmer and drier. Lake Bonneville began to shrink due to increased evaporation. Today's Great Salt Lake is a large remnant of Lake Bonneville, and occupies the lowest depression in the Great Basin. Who discovered Great Salt Lake? o The Spanish missionary explorers Dominguez and Escalante learned of Great Salt Lake from the Native Americans in 1776, but they never actually saw it. The first white person known to have visited the lake was Jim Bridger in 1825. Other fur trappers, such as Etienne Provost, may have beaten Bridger to its shores, but there is no proof of this. The first scientific examination of the lake was undertaken in 1843 by John C. Fremont; this expedition included the legendary Kit Carson. A cross, carved into a rock near the summit of Fremont Island, reportedly by Carson, can still be seen today. Why is the Great Salt Lake salty? o Much of the salt now contained in the Great Salt Lake was originally in the water of Lake Bonneville. Even though Lake Bonneville was fairly fresh, it contained salt that concentrated as its water evaporated. A small amount of dissolved salts, leached from the soil and rocks, is deposited in Great Salt Lake every year by rivers that flow into the lake. About two million tons of dissolved salts enter the lake each year by this means. Where does the Great Salt Lake get its water, and where does the water go? o Great Salt Lake receives water from four main rivers and numerous small streams (66 percent), direct precipitation into the lake (31 percent), and from ground water (3 percent). -

Space and Social Structure in the A.D. 13th Century Occupation of Promontory Cave 1, Utah by Courtney D. Lakevold A thesis submitted in partial fulfillment of the requirements for the degree of Master of Arts Department of Anthropology University of Alberta © Courtney D. Lakevold, 2017 ABSTRACT Promontory Cave 1, located on the north shore of Great Salt Lake in northern Utah, has yielded many extraordinary archaeological artifacts that are amazingly well-preserved. Promontory phase deposits in Cave 1 are extremely thick, and rich with perishables and other material culture. Bison bones, fur, leather and hide processing artifacts have been recovered at the site, in addition to gaming pieces, basketry, pottery, juniper bark for bedding, knife handles, ceramics and moccasins. A large central hearth area, pictograph panels, pathways and entrance and exit routes have also been identified. Bayesian modeling from AMS dates indicates a high probability that the cave was occupied for one or two human generations over a 20-50 year interval (A.D. 1240-1290). Excavations have taken place at the cave from 2011-2014 by an interdisciplinary research team with members from the University of Alberta (Institute of Prairie Archaeology), the Natural History Museum of Utah (NHMU), Oxford, the Desert Research Institute and Brigham Young University. The extraordinary preservation and narrow time frame (A.D. 1240-1290) for the occupation of Promontory Cave 1 on Great Salt Lake allow for unusual insights into the demography of its Promontory Culture inhabitants. This thesis looks at the cave as a humanly inhabited space and examines what the Promontory Culture group may have looked like in terms of population size and group composition, and how they used or organized space in the cave.
