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.

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.

Book excerpt: Positive Train Control Systems (US Federal Railroad Administration Regulation) (FRA) (2018 Edition) The Law Library presents the complete text of the Positive Train Control Systems (US Federal Railroad Administration Regulation) (FRA) (2018 Edition). Updated as of May 29, 2018 FRA proposes regulations implementing a requirement of the Rail Safety Improvement Act of 2008 that certain passenger and freight railroads install positive train control systems. The proposal includes required functionalities of the technology and the means by which it would be certified. The proposal also describes the contents of the positive train control implementation plans required by the statute and contains the proposed process for submission of those plans for review and approval by FRA. These proposed regulations could also be voluntarily complied with by entities not mandated to install positive train control systems. This book contains: - The complete text of the Positive Train Control Systems (US Federal Railroad Administration Regulation) (FRA) (2018 Edition) - A table of contents with the page number of each section
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: 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. 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.

Download or read book Positive Train Control written by and published by . This book was released on 2005 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rail Safety Improvement Act of 2008 (RSIA) established a completion date for the installation of interoperable Positive Train Control (PTC) systems by December 31, 2015. The RSIA also required the Secretary of Transportation to transmit a report to specified congressional committees no later than December 31, 2012, on the progress of the railroad carriers in implementing such PTC systems. This report satisfies the statutory reporting requirement...Based on the results of this report, FRA believes that the majority of railroads will not be able to complete PTC implementation by the 2015 deadline. Partial deployment can likely be achieved; however, the extent of which is dependent upon the successful resolution of any known and emergent issues. As a result, FRA recommends that if Congress were to consider legislation extending the PTC implementation deadline it should consider several factors, including the extent to which each railroad has demonstrated due diligence in its efforts to successfully implement PTC technologies on its rail system. In the event that Congress were to make legislative changes, FRA suggests allowing for provisional certification of PTC systems that will allow for the use of installed PTC systems under controlled conditions before final system certification is complete. This will allow for the incremental use of PTC systems and produce an increase in safety as the systems are systematically rolled out. FRA also suggests that any revisions to a railroad’s PTCIP be subject to FRA approval with sufficient time for FRA to review and significant FRA oversight. Finally, FRA recommends that it be allowed to approve a railroad to use alternative safety technologies on specified line segments in lieu of PTC, particularly in areas with lower safety risks, if appropriately and properly justified to FRA.

Available in PDF, EPUB and Kindle. Book excerpt: The North American Joint Positive Train Control (NAJPTC), was an ambitious project to develop, test, and demonstrate PTC capabilities, including flexible block operations, interoperability, and advance activation of highway grade crossing devices, in a corridor with both freight and passenger service. The projects safety objectives were to: (a) prevent train-to-train collisions (positive train separation), (b) enforce speed restrictions, including civil engineering restrictions and temporary slow orders, and (c) provide protection for roadway workers and their equipment operating under specific authorities. Additionally, the project would provide for industry interoperability, demonstrate safe operation of locomotives equipped with interoperable systems, and implement moving block functionality. The project would provide a cost-effective design in order to enhance prospects for deployment.
