Keeping Track of Track Geometry

Railway infrastructure management involves a high degree of complexity. Economic, legal, political and, above all, technical interdependencies are required. The aim of the Best Practice Permanent Way Maintenance series is to describe these relationships in a structured way for all stakeholders. "Infrastructure Management" looks at aspects of infrastructure management with particular reference to the single European railway area. Based on best-practice examples from Central Europe, measures for the targeted retrofitting and improvement of the infrastructure maintenance of the existing network are presented. In many places, infrastructure operators are faced with a generational change, which accelerates the process. Modern information and communication technology can simplify the comprehension and presentation of complex contexts. Modified approaches to asset management and life-cycle management enable implementation of the "transparent permanent way" or the "railway 4.0".

Railway track infrastructure is a complex system consisting of various subsystems which require incremental maintenance from all engineering disciplines; all of whom are competing for the limited time and number of available maintenance windows. The constant demand for higher traffic volumes, increased train speeds and heavier axle loadings all result in an exponential increase in maintenance requirements but the time available for maintenance is as a result even further reduced. This requires a more scientific lifecycle approach to infrastructure maintenance management. It also requires increased performance from mechanised construction, maintenance and renewal machines to keep the infrastructure reliable, available, maintainable, affordable and safe within the short available maintenance windows. The objectives of this book are to address the optimisation of infrastructure maintenance management and to provide a model with selection criteria for maintenance machinery and their features for the prevailing circumstances The included e-book provides users of a device with pdf-reader (PC, tablet, smartphone) the contents of the work also electronically and with search function.

This book is dedicated to the many people involved in the day to day planning and performance of track maintenance activities. Providing a practical approach to everyday challenges in mechanised track maintenance, it is not just intended as a theoretical approach to the track system. Railways aim at transporting people and freight safely, rapidly, regularly, comfortably and on time from one place to another. This book is directed to track infrastructure departments contributing to the above objective by ensuring the track infrastructure’s reliability, availability, maintainability and safety – denoted by the acronym RAMS. Regular, effective and affordable track maintenance enable RAMS to be achieved. As a social service, railways are required to transport people at affordable fares. On freight railways, transportation costs significantly influence the competitiveness of products, particularly when it comes to exports. The “affordability” of maintenance activities should therefore be added to RAMS, hence RAMAS, since operating and capital funds are a major stumbling block for effective maintenance practice. As a result, alternative methods and technologies will always be sought after. This has given rise to the term “appropriate” technology as opposed to “latest” or “best” technology. Maintenance strategies and methods play a major role in ensuring the RAMAS of the railway as they involve decisions on the track sections to be maintained, the maintenance measures to be taken, the resources available for maintenance and the use of appropriate maintenance machinery. The focus of this book is therefore placed on reliability, availability, maintainability, affordability and safety as objectives of track maintenance.

Basics - Error Detection - Correction - Quality: A comparative overview of the DACH countries and the UK  Language: Japanese! This technical book provides a comprehensive, practical overview of all aspects of track alignment correction, taking into account the relevant regulations of the DACH countries (Germany, Austria and Switzerland) and the United Kingdom. First of all, the fundamentals of track alignment and the interrelationships between track components and their stresses are described in a clear and practical manner. Starting from these fundamentals of track alignment, the book then spans the thematic arc from the determination to the methods of measurement and correction of track position defects to quality control. The entire tamping process, including all the necessary accompanying work, is explained clearly and independently of the manufacturer. Regardless of the existing level of knowledge, this book offers interested parties from all areas of railway engineering an insight into the planning, execution and acceptance of tamping work in the DACH countries and the UK. The six chapters of this book not only provide a well-founded introduction to the basic aspects of railway track and track construction, but also give a comparison of the engineering principles adopted in these four countries. This comparison provides an interesting insight into the practical implementation of those technical principles and illustrates common features as well as differences. From the legal provisions to the basics of the permanent way as well as measurement methods, the book describes the key concepts that are required for the design and maintenance of track geometry on plain line track.
