Best Practice in Track Maintenance, Vol 1 - Infrastructure Management

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.

Basics - Error Detection - Correction - Quality: A comparative overview of the DACH countries and the UK  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.
