Book Description
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.

Book Description
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 Description
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.

Book Description
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 Description
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.

Book Description
Trains are massive—with some weighing 15,000 tons or more. When these metal monsters collide or go off the rails, their destructive power becomes clear. In this book, George Bibel presents riveting tales of trains gone wrong, the detective work of finding out why, and the safety improvements that were born of tragedy. Train Wreck details 17 crashes in which more than 200 people were killed. Readers follow investigators as they sift through the rubble and work with computerized event recorders to figure out what happened. Using a mix of eyewitness accounts and scientific explanations, Bibel draws us into a world of forensics and human drama. Train Wreck is a fascinating exploration of• runaway trains• bearing failures• metal fatigue• crash testing • collision dynamics• bad rails

Book Description
In simple, powerful words and vibrant illustrations, Donald Crews evokes the rolling wheels of that childhood favorite: a train. This Caldecott Honor Book features bright colors and bold shapes. Even a child not lucky enough to have counted freight cars will feel he or she has watched a freight train passing after reading Freight Train. Donald Crews used childhood memories of trains seen during his travels to his grandparents' farm in the American South as the inspiration for this timeless favorite. New York magazine's The Strategist chose Freight Train as one of the "Best (Nonobvious) Baby Books to Bring to a Shower." As The Strategist stated: "The Caldecott Honor Book is spare and minimal in both art and text and follows the journey of a freight train and all its cars until it rolls off the page and into the distance. It’s a good way to learn all the different names of train cars, too." Red caboose at the back, orange tank car, green cattle car, purple box car, black tender and a black steam engine . . . freight train.
