Book Description
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.

Book Description
The use of concrete sleepers in railways started in the 1940s. They are currently used in many countries thoughout the world at a rate of over 12 million per year. This report discusses the various types of sleeper which have been developed - monoblock, two-block, reinforced and prestressed concrete. Separate sections deal with design, rail fastening systems, manufacture, quality control and testing, installation and performance, and research and development.

Book Description
By far the greatest proportion of the total cost of maintaining the infrastructure of a railway arises from the track, Modern trains are lighter, travel faster and are much easier to derail than before. Therefore it is vital that track is maintained adequately.This volume shows how railways can be kept running using the minimum necessary maintenance, taking into account the environmental conditions and the type and volume of traffic using the railway.

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.

Book Description
Never before has a comprehensive history been written of the track used by railways of all gauges, tramways, and cliff railways, in Great Britain. And yet it was the development of track, every bit as much as the development of the locomotive, that has allowed our railways to provide an extraordinarily wide range of services. Without the track of today, with its laser-guided maintenance machines, the TGV and the Eurostar could not cruise smoothly at 272 feet per second, nor could 2,000-ton freight trains carry a wide range of materials, or suburban railways, over and under the ground, serve our great cities in a way that roads never could. ??Andrew Dow's account of the development of track, involving deep research in the papers of professional institutions as well as rare books, company records and personal accounts, paints a vivid picture of development from primitive beginnings to modernity. ??The book contains nearly 200 specially-commissioned drawings as well as many photographs of track in its very many forms since the appearance of the steam locomotive in 1804. Included are chapters on electrified railways, and on the development of mechanised maintenance, which revolutionised the world of the platelayer.
