Book excerpt: Positive Train Control (PTC) is a communications and signalling system that has been identified by the National Transportation Safety Board (NTSB) as a technology capable of preventing accidents caused by train operator or dispatcher error. PTC is expected to reduce the number of accidents due to excessive speed, conflicting train movements, and engineer failure to obey wayside signals. The Rail Safety Improvement Act of 2008 (RSIA08) requires implementation of positive train control on railroads which carry passengers or have high-volume freight traffic with toxic or poisonous-by-inhalation hazardous materials. This book provides an overview of the issues and economics for improved rail safety. While PTC promises benefits in terms of safety, its implementation entails substantial costs and presents a variety of other policy-related issues. These include the interoperability of individual railroads' systems, sufficient radio spectrum to support PTC, and the possibility that PTC could be a barrier to market entry.

This book was released on 2012-05-31 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human errors, as well as deliberate sabotage, pose a considerable danger to passengers riding on the modern railways and have created disastrous consequences. To protect civilians against both intentional and unintentional threats, rail transportation has become increasingly automated. Railway Safety, Reliability, and Security: Technologies and Systems Engineering provides engineering students and professionals with a collection of state-of-the-art methodological and technological notions to support the development and certification of real-time safety-critical railway control systems, as well as the protection of rail transportation infrastructures.
Download or read book Track Design Handbook for Light Rail Transit written by and published by Transportation Research Board. This book was released on 2012 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.
Download or read book Energy Efficient Train Control written by Philip G. Howlett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rail is potentially a very efficient form of transport, but must be convenient, reliable and cost-effective to compete with road and air transport. Optimal control can be used to find energy-efficient driving strategies for trains. This book describes the train control problem and shows how a solution was found at the University of South Australia. This research was used to develop the Metromiser system, which provides energy-efficient driving advice on suburban trains. Since then, this work has been modified to find practical driving strategies for long-haul trains. The authors describe the history of the problem, reviewing the basic mathematical analysis and relevant techniques of constrained optimisation. They outline the modelling and solution of the problem and finally explain how the fuel consumption can be minimised for a journey, showing the effect of speed limits and track gradients on the optimal driving strategy.
Download or read book Positive Train Control written by Susan A. Fleming and published by . This book was released on 2013-10-17 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the wake of a 2008 commuter train collision that resulted in 25 fatalities, the Rail Safety Improvement Act of 2008 (RSIA) was enacted. It requires major freight railroads, Amtrak, and commuter railroads to install positive train control (PTC) on many major routes by the end of 2015. PTC implementation, overseen by the Federal Railroad Administration (FRA), is a complex endeavor that touches almost every aspect of train operations on major lines. According to FRA, 37 railroads are required to implement PTC. This report examined the status of PTC implementation. It discusses, among other things, railroads' implementation of PTC to date and the challenges, if any, to meeting the 2015 deadline. Tables and figures. This is a print on demand report.

Book excerpt: From the 1830s to today, the railroad industry has developed myriad complex mechanisms to help keep North America’s railroad rights-of-ways safe, efficient, and relatively accident-free. In this paperback rerelease of the successful 2003 title, the otherwise-arcane world of railroad signaling is explained in concise language and brought to life with nearly 200 fantastic photographs that depict signaling history and all aspects of modern operations. Author and photographer Brian Solomon brings his wealth of knowledge and photographic talent to a subject that has not often been tackled in book form, yet is integral to the American railroad experience.

Book excerpt: The Rail Safety Improvement Act of 2008 mandated that certain railroads implement positive train control (PTC) by December 31, 2015. In prior work, GAO found that most railroads reported that they will miss this deadline due to numerous interrelated challenges caused by the breadth and complexity of PTC. This report reviewed the progress of implementation since 2013. It examines (1) progress railroads have made in implementation and in addressing challenges; and (2) how the Federal Railroad Administration (FRA) has overseen implementation. Tables and figure.

Download or read book Homage to Catalonia written by George Orwell and published by E-Kitap Projesi & Cheapest Books. This book was released on 2023-11-27 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homage to Catalonia is George Orwell's personal account of his experiences and observations fighting for the POUM militia of the Republican army during the Spanish Civil War. The war was one of the defining events of his political outlook and a significant part of what led him to write in 1946, "Every line of serious work that I have written since 1936 has been written, directly or indirectly, against totalitarianism and for Democratic Socialism, as I understand it." The first edition was published in the United Kingdom in 1938. The book was not published in the United States until February 1952, when it appeared with an influential preface by Lionel Trilling. The only translation published in Orwell's lifetime was into Italian, in December 1948. A French translation by Yvonne Davet-with whom Orwell corresponded, commenting on her translation and providing explanatory notes-in 1938-39, was not published until five years after Orwell's death. Book Summary: Orwell served as a private, a corporal (cabo) and-when the informal command structure of the militia gave way to a conventional hierarchy in May 1937-as a lieutenant, on a provisional basis, in Catalonia and Aragon from December 1936 until June 1937. In June 1937, the leftist political party with whose militia he served (the POUM, the Workers' Party of Marxist Unification, an anti-Stalinist communist party) was declared an illegal organisation, and Orwell was consequently forced to flee. Having arrived in Barcelona on 26 December 1936, Orwell told John McNair, the Independent Labour Party's (ILP) representative there, that he had "come to Spain to join the militia to fight against Fascism." He also told McNair that "he would like to write about the situation and endeavour to stir working class opinion in Britain and France." McNair took him to the POUM barracks, where Orwell immediately enlisted. "Orwell did not know that two months before he arrived in Spain, the [Soviet law enforcement agency] NKVD's resident in Spain, Aleksandr Orlov, had assured NKVD Headquarters, 'the Trotskyist organisation POUM can easily be liquidated'-by those, the Communists, whom Orwell took to be allies in the fight against Franco."
