Precast Concrete Railway Track Systems by fib Fédération internationale du béton Pdf

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.

Concrete Railway sleepers by FIB – International Federation for Structural Concrete Pdf

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.

Practical Railway Engineering by Clifford F. Bonnett Pdf

This textbook covers the very wide spectrum of all aspects of railway engineering for all engineering disciplines, in a 'broad brush' way giving a good overall knowledge of what is involved in planning, designing, constructing and maintaining a railway. It covers all types of railway systems including light rail and metro as well as main line. The first edition has proved very popular both with students new to railways and with practicing engineers who need to work in this newly expanding area.In the second edition, the illustrations have been improved and brought up to date, particularly with the introduction of 30 colour pages which include many newly taken photographs. The text has been reviewed for present day accuracy and, where necessary, has been modified or expanded to include reference to recent trends or developments. New topics include automatic train control, level crossings, dot matrix indicators, measures for the mobility impaired, reinforced earth structures, air conditioning, etc. Recent railway experience, both technical and political, has also been reflected in the commentary.

Mechanics of Ballasted Rail Tracks by Buddhima Indraratna,Wadud Salim Pdf

In this book, the authors discuss testing of ballast, including the strength, deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast has also been examined. A new stress-strain constitutive model for ballast incorporating particle breakage is presented. Finally, a new range of particle gradations, balancing the strength and permeability requirements, has been proposed for future rail tracks. This book is intended as a reference text for final year civil engineering students and postgraduates, and for practicing railway engineers with the task of modernizing existing designs.

The Urban Rail Development Handbook by Daniel Pulido,Georges Darido,Ramon Munoz-Raskin,Joanna Moody Pdf

Cities across the globe are looking to develop affordable, environmentally friendly, and socially responsible transportation solutions that can meet the accessibility needs of expanding metropolitan populations and support future economic and urban development. When appropriately planned and properly implemented as part of a larger public transportation network, urban rail systems can provide rapid mobility and vital access to city centers from surrounding districts. High-performing urban rail services, when carefully approached as development projects, can help enhance quality of life by giving citizens access to employment opportunities, essential services, urban amenities, and neighboring communities. The purpose of this Handbook is to synthesize and disseminate knowledge to inform the planning, implementation, and operations of urban rail projects with a view towards: -- Emphasizing the need for early studies and project planning; -- Making projects more sustainable (economically, socially, and environmentally); -- Improving socioeconomic returns and access to opportunities for users; -- Maximizing the value of private participation, where appropriate; and -- Building capacity within project implementing and managing institutions This Handbook provides experiential advice to tackle the technical, institutional, and financial challenges faced by decision makers considering urban rail projects. It brings together the expertise of World Bank staff and the input of numerous specialists to synthesize international 'good practices' and recommendations that are independent of commercial, financial political, or other interests. The material presented is intended as an honest-broker guide to maximize the impact and manage the challenges of urban rail systems in cities in both developed and developing countries. Rather than identify a single approach, this Handbook acknowledges the complexities and context necessary when approaching an urban rail development by helping to prepare decision makers to ask the right questions, consider the key issues, perform the necessary studies, apply adequate tools, and learn from international good practice all at the right time in the project development process.
