This fascinating, well-illustrated and informative book presents a straightforward guide to points, signals and level crossings and provides all the information that railway modellers need in order to get the trains on their layouts moving effectively. The history of semaphore and colour light signals is outlined and the implications for modellers is clearly explained. A variety of different types of points, signals and level crossings is then illustrated with detailed instructions describing how to make them work. Simple, tried and tested mechanical and electrical methods used by modellers are explained together with modern electronic approaches, which are described in a way that enables them to be easily understood. The reader is taken step-by-step through various projects, and clear diagrams and photographs are provided throughout, including wiring diagrams for frogs, signals and level crossings. Written by an electronic engineer, this book contains invaluable information gained in a lifetime's experience of railway modelling and will help both the new and the experienced railway modeller to understand electronic and electrical concepts and bring their model railways to life. Fully illustrated with 156 colour diagrams and colour photographs.
TCRP report 155 provides guidelines and descriptions for the design of various common types of light rail transit (LRT) track. The track structure types include ballasted track, direct fixation ("ballastless") track, and embedded track. The report considers the characteristics and interfaces of vehicle wheels and rail, tracks and wheel gauges, rail sections, alignments, speeds, and track moduli. The report includes chapters on vehicles, alignment, track structures, track components, special track work, aerial structures/bridges, corrosion control, noise and vibration, signals, traction power, and the integration of LRT track into urban streets.
Rail-bound transport in urban areas plays an important role in public transport. Given its urban setting, urban rail-bound transport can be significantly influenced by the interfering road traffic around it. Considering the capacity and operation quality of urban rail-bound transport influenced by road traffic in various urban mixed traffic zones, it'very important to investigate and include the road traffic influences for capacity research on urban rail-bound transport. In this dissertation, two approaches are developed to model the road traffic influences according to the analysis of the interactions between urban mixed traffic in various mixed traffic zones. As an important intermediate result, the newly-developed waiting time function is determined to adapt to an urban rail-bound system with consideration of external influences. Furthermore, an algorithm is developed in the model with an event-driven system to simulate the interactions among urban mixed traffic in various mixed traffic zones. This algorithm is used to assess the significance of mixed traffic impacts and derive the primary results for capacity research.
Human factors and ergonomics have made considerable contributions to the research, design, development, operation and analysis of transportation systems and their complementary infrastructure. This volume focuses on the causations of road accidents, the function and design of roads and signs, the design of automobiles, and the training of the driver. It covers accident analyses, air traffic control, control rooms, intelligent transportation systems, and new systems and technologies.
In a rapidly changing world, with increasing competition in all sectors of transportation, railways are currently restructuring their planning, management, and technology. As commercial and pricing policies change and new methods of organization are introduced, a more entrepreneurial spirit is required. At the same time, new high-speed tracks are being constructed and old tracks are being renewed, magnetic levitation trains are in operation, hyperloop systems are being planned, high-comfort rolling stock vehicles are being introduced, logistics and combined transport are being developed. Awareness of environmental issues and the search for greater safety attribute a new role to the railways within the transportation system. Meanwhile, methods of analysis have evolved significantly, principally due to computer applications, the internet revolution, satellite technologies, and artificial intelligence, all of which offer new ways of thinking about and addressing old problems. Railway Planning, Management, and Engineering aims to fulfill the need for a new scientific approach for railways. It is intended to be of use to railway planners, managers, economists, engineers, and students in engineering, transportation, economics, and management. The book is divided into three parts, which deal successively with planning, management, track, rolling stock, safety, and the environment.
