Buch. Condición: Neu. Neuware -SYNOPSISThis 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 intended as a theoretical approach to the track system. RAMS and railways 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. 308 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -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. The included Elektronisches Buch provides users of a device with pdf-reader (PC, tablet, smartphone) the contents of the work also electronically and with search function. 224 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The performance of many railway networks and the quality of service offered is becoming more and more critical. The main issues to be addressed are the increasing traffic volumes and making the best use of the available capacity, at the same time resolving train scheduling and management problems.This is an updated, revised and extended edition of 'Railway Timetable & Traffic', published in 2008. It describes the state-of-the-art methods of railway timetabling and optimisation, capacity estimation, train operations analysis and modelling, simulation, rescheduling and performance assessment. The intention is to stimulate their broader application in practice and to highlight current and future research areas. It is directed at academics, Masters and PhD students, as well as professionals from the railway industry. It will also be of interest to the public authorities that tender, monitor and perhaps fund railway service provision. The overall aim is to improve the attractiveness and efficiency of the train services which can be offered to the public.The key to achieving a higher efficiency and quality of train operations is an awareness of the impact of availability, reliability and robustness of the subsystems on train processes. A deeper insight into the probability of incidents and the propagation of train delays depends on a thorough analysis of real world railway operations and the feedback obtainable. This leads to an optimisation of the timetable and a network-wide improvement in traffic management performance. This know-how should increase the efficiency of the railway system, making it more attractive for regular, occasional and new customers, and ensure that the railways continue to innovate. They will then be able to make the maximum contribution possible to the transport needs of the future. 332 pp. Englisch.

Buch. Condición: Neu. Neuware -European Train Control System (ETCS) is now a well-established standard manufactured by multiple suppliers and installed widely on trains and tracks in Europe and around the world.High level information about ETCS is readily available in magazine articles and websites, and the detailed specifications are also publicly available from the European Agency for Railways (ERA). Our aim with this book is to fill the gap between these, explaining the background and technical detail in a manner that will be understandable to an engineer who is new to ETCS.The main topics of the book are:¿ Introduction to ETCS, its history, stakeholders, governance, benefits¿ Concepts and functionality, including levels, modes, operational scenarios¿ Constituents and interfaces, on the track and on the train¿ Deployment in projects, testing, certification, training and entry into serviceReaders of this book will include:¿ Students and early career professionals, including those studying for qualifications such as the IRSE Advanced Diploma in Railway Control Engineering and the Certificate in Railway Control Engineering Fundamentals¿ Signal engineers encountering ETCS is a project for the first time¿ Engineers working in specific ETCS roles who need a wider understanding of the system¿ Railway operations staff involved with changes to operational rules and training for the deployment of ETCS¿ Railway managers and consultants interested in the opportunities and challenges that ETCS can bring to their strategies for railway development or renewalsThis book has been prepared by a working group of the Institution of Railway Signal Engineering (IRSE) drawing on experience from a wide range of engineers who have worked for railways and suppliers as the system has been developed.The IRSE is the professional institution for all those engaged in railway signalling and telecommunications, train control, traffic management and allied professionals, with 5,000 members around the world.Railway signalling is responsible for managing the safe flow of train traffic, and modern systems are based on digital track to train communications. Implementing this technology on the complex European railway network has required the development of a standard interoperable solution that is applicable to all types of railway traffic and allows trains to operate across national borders.Bonus for free: The Elektronisches Buch-PDF of this book is available upon registration.

Buch. Condición: Neu. Neuware -Immer mehr Züge fahren auf unseren Gleisen, wodurch das Bahnsystem an seine Grenzen gerät. Hinzu kommt eine hohe Anzahl an Altsystemen, die dieses System weiter belasten. Gleichzeitig ist Bahnfahren jedoch einer der wichtigsten Bausteine für die Verkehrswende und den Klimaschutz. Für einen attraktiveren Bahnverkehr mit mehr Zügen in einer höheren Qualität muss das System Bahn durch tiefgreifende, technologische Innovationen grundlegend modernisiert werden. Deshalb hat die Sektorinitiative Digitale Schiene Deutschland es sich zur Aufgabe gemacht, mehr Kapazitäten im Schienennetz zu schaffen und damit Qualität und Pünktlichkeit zu verbessern.Das gesamte Bahnsystem zu modernisieren und zu digitalisieren, ist eine große Herausforderung. Damit die Digitale Schiene Deutschland ihren Beitrag zur Verkehrswende und zum Klimaschutz leisten kann, ist es wichtig, dass der gesamte Sektor gemeinsam mit der Politik an einem Strang zieht. Nur so kann das System Bahn im Zeitalter der Digitalisierung ankommen und europaweit zum Vorreiter für das Digitale Bahnsystem werden. Deshalb investieren wir nicht nur in die Digitalisierung der Infrastruktur, sondern auch in die Forschung und Entwicklung zukünftiger Technologien. Dieses Buch zeigt jene Maßnahmen, die bereits umgesetzt werden, aber auch neu entwickelte Technologien. Es zeigt auch die Herausforderungen, die auf unserem Weg liegen, bis die Vision der Digitalen Schiene Deutschland vollständig Realität wird. 141 pp. Deutsch.
