The Railway Track and Its Long Term Behaviour


Book Description

A proper quality of a track and other infrastructure objects represents a basic requirement for train safety and punctuality. Most of the physical systems and their components deteriorate over time. This affects performance and may lead to failures. Albert Einstein said, “You have to learn the rules of the game. And then you have to play better than anyone else.” Only if we understand how the whole system works, taking into account its imperfections and how they influence its quality and performance will we be able to learn the rules of the game and “play better.” The book provides the readers with the necessary functional knowledge of track behaviour and comprehensively covers the function of the various track components, their interaction as elements of the track system, as well as the interaction of the track with railway vehicles. By presenting important tools for a deep understanding of track-behaviour this book aims to be a reference guide for infrastructure managers and to help them to find ways improving track quality for optimum long-term behaviour.




Track Design Handbook for Light Rail Transit


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.







Track and Track Laying in Railway Modelling


Book Description

Planning, designing and laying the track for a model railway layout can be challenging, especially if you have never done it before. This book provides a step-by-step guide to the techniques required and methods used in track design and layout. With content suitable for those who are new to the hobby through to the more experienced modeller, and some 200 images, it includes: an overview of the various forces that act on prototype railways and which determine the design of trackwork. The planning and designing of layouts, including the pros and cons of different domestic locations are covered along with baseboard construction for both portable and permanent layouts. There is a review of the track systems available and how to lay tracks, the tools and skills required, and problem solving. Wiring up both analogue (DC) and digital layouts (DCC), with diagrams are given and scales and gauges are discussed. Finally, there are hints and tips on ballasting and weathering track.




Engineering Iron and Stone


Book Description

Boothby presents a comprehensive explanation of the empirical, graphical, and analytical design techniques used during the late nineteenth century in the construction of both buildings and bridges in wood, stone, brick, and iron.










Understanding Measures of Faculty Impact and the Role of Engineering Societies


Book Description

On January 26, 2017, the National Academy of Engineering (NAE), with support from the National Science Foundation (NSF), held a workshop in Washington, DC, on the engagement of engineering societies in undergraduate engineering education. Since then, the NAE has held a series of follow-up regional workshops to investigate specific issues identified in the January 2017 workshop as deserving of further discussion and evaluation. The second in this series of supplemental workshops was held on February 12, 2018. It brought together about 45 representatives of professional societies, academic institutions, and businesses to explore the role of engineering societies in enhancing understanding of faculty impact on the engineering profession as part of the reappointment, promotion, and tenure (RPT) process. This publication summarizes the presentations and discussions from the workshop.




Site Reliability Engineering


Book Description

The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use
