Due to increasing traffic flows the extension of transport infrastructure with rail roads and high speed lines is an ongoing process worldwide. Ballastless track systems with concrete slabs are used more and more. Following the first trials in the 1970s and more than four decades of R&D work on ballastless track, the level of development is such that it can be confirmed that ballastless track is suitable for use as an alternative to ballasted track. This book makes a contribution to the state of the art of ballastless track by describing the basics for designing the ballastless track. Important advice is provided regarding the construction of ballastless track on earthworks and in tunnels. There is also a description of the technical history of the development of ballastless track on bridges and the ensuing findings for bridge design. The state of the art of ballastless track for switches, important information on details concerning drainage, transitions, accessibility for road vehicles and experience gleaned from maintenance round off the work. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

The transport sector consists of different modes of transport, each serving a growing demand for transporting people and goods. This (growing) demand on the one hand, needs expanding the systems’ capacity, and on the other hand, increasing the corresponding economic efficiency, effectiveness, and environmental and social friendliness. This implies development of a ‘greener’, i.e. a more sustainable transport sector. The book describes the current and prospective state of the art analytical modelling, conceptual planning, and multi-criteria evaluation of the selected cases of transport systems operated by different transport modes such as road, rail, sea, air, and intermodal. As such, the book is unique in addressing these three important aspects of dealing with transport systems before implementation of their particular components means by the selected cases. It will be particularly useful for readers from the academia and the professionals from the transport sector.

In 1986, the FIP Commission on Prefabrication issued the state-of-art report "Concrete Railway Sleepers", which included design considerations, manufacturing methods, rail fastening systems and field performance. During the two decades since that report, precast concrete has gained importance in the field of railway track systems for plain track, switches and crossings, tunnels and other applications. Developments in production methods for concrete sleepers in switch and crossing layouts to cope with the complex geometry and the industry's confidence in their performance have contributed to the huge increase in the use of this type of sleeper. The use of slab track for high-speed track has also grown, particularly where either new track is built or where existing track is renewed and long periods of track possession are possible. There has also been progress in the development of plant and equipment for the installation, renewal and maintenance of concrete sleepered track. With machines now able to replace existing track at a rate of 5000 sleepers (over 3 km track) per day, choosing concrete sleepers can reduce the time on site, meaning tracks can be reopened quickly whilst reducing labour requirements and costs. Today, precast concrete is considered to be the best performing and preferred material for railway sleepers, due to the following factors: long-term durability; improved geometric retention of track and greater weight vital for high-speed and heavy freight lines; improved elasticity of track; improved ride quality; low first cost; minimum life cycle cost; low cost of maintenance; environmental friendliness - no chemical treatment required and can be recycled. As all aspects of precast concrete railway track systems, from design through manufacture to installation and maintenance, have progressed since the publication of the FIP report, an update was considered timely, in order to provide a synthesis of currently available information. This new edition covers quality, design, production, durability, maintenance and environmental considerations, and includes survey on the use of precast concrete track systems in over 30 countries.
