This book was released on 2013-01-26 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Towards optimal railway track utilization based on societal benefit written by Victoria Svedberg and published by Linköping University Electronic Press. This book was released on 2018-10-12 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrastructure managers in railway systems are striving to have as e?cient track utilization as possible. There are no unanimous interpretation of e?ciency in terms of track utilization, but the aim of the Swedish Transport Administration is to allocate track capacity such that societal bene?t is maximized. This means that the tracks should be used by as much tra?c as possible and by tra?c that provides as much bene?t for the society as possible. To allocate track capacity such that the track utilization is optimal would be an easy task if the track capacity were not a scarce resource. Today, many train operators share railway network and there are cases when two or more operators want to use the same track capacity at the same time. The infrastructure manager must then make priorities and reject some operators, and the question is which operators to reject. The guiding principle is to grant the operators that provide the highest societal bene?t access to the tracks. However, the question would then change into how to know which operator that provides the highest societal bene?t. In this thesis, the societal bene?t of publicly subsidized tra?c is estimated using social cost-bene?t analysis. Mathematical models and methods are developed for quantifying and computing the number of departures for the publicly subsidized tra?c and their distribution in time, i.e. a train timetable, that provides the maximal societal bene?t in a social cost-bene?t analysis setting. The societal bene?t of commercial tra?c is estimated using the market value for their requested train timetables. The market value is set using dynamic pricing. A suggestion of a dynamic pricing process that can be used in the train timetabling process is described. Mathematical models and methods for calculating the supply and demand of a track access request are developed and tested, which enables the use of a dynamic pricing process on track capacity

Download or read book System Dynamics and Long Term Behaviour of Railway Vehicles Track and Subgrade written by Karl Popp and published by Springer Science & Business Media. This book was released on 2013-06-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decades completely new technologies for high speed railway vehicles have been developed. The primary goals have been to increase traction, axle load, and travelling speed, and to guarantee the safety of the passengers. However, new developments have revealed new limitations: settlement and destruction of the ballast and the subgrade lead to deterioration of the track; irregular wear of the wheels causes an increase in overall load and deterioration in passenger comfort; and damage of the running surfaces of the rail and the wheel is becoming more frequent. These problems have been investigated in the Priority Programme SPP 1015 supported by the Deutsche Forschungsgemeinschaft (DFG), with the goal of better understanding of the dynamic interaction of vehicle and track, and the long-term behavior of the components of the system. The book contains the scientific results of the programme as presented at the concluding colloquium held at University of Stuttgart, Germany, 2002.

Available in PDF, EPUB and Kindle. Book excerpt: Planning, designing and laying the track for a model railway layout can be challenging, especially if you have never done it before. This book provides a step-by-step guide to the techniques required and methods used in track design and layout. With content suitable for those who are new to the hobby through to the more experienced modeller, and some 200 images, it includes: an overview of the various forces that act on prototype railways and which determine the design of trackwork. The planning and designing of layouts, including the pros and cons of different domestic locations are covered along with baseboard construction for both portable and permanent layouts. There is a review of the track systems available and how to lay tracks, the tools and skills required, and problem solving. Wiring up both analogue (DC) and digital layouts (DCC), with diagrams are given and scales and gauges are discussed. Finally, there are hints and tips on ballasting and weathering track.

Download or read book Tracks Across Continents Paths Through History written by Douglas J. Puffert and published by University of Chicago Press. This book was released on 2009-04 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: A standard track gauge—the distance between the two rails—enables connecting railway lines to exchange traffic. But despite the benefits of standardization, early North American railways used six different gauges extensively, and even today breaks of gauge at national borders and within such countries as India and Australia are expensive burdens on commerce. In Tracks across Continents, Paths through History, Douglas J. Puffert offers a global history of railway track gauge, examining early choices and the dynamic process of diversity and standardization that resulted. Drawing on the economic theory of path dependence, and grounded in economic, technical, and institutional realities, this innovative volume traces how early historical events, and even idiosyncratic personalities, have affected choices of gauge ever since, despite changing technology and understandings of what gauge is optimal. Puffert also uses this history to develop new insights in the theory of path dependence. Tracks across Continents, Paths through History will be essential reading for anyone interested in how history and economics inform each other.

Download or read book Advanced Rail Geotechnology Ballasted Track written by Buddhima Indraratna and published by CRC Press. This book was released on 2023-08-14 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ballast plays a vital role in transmitting and distributing the train wheel loads to the underlying track substructure. The load-bearing capacity, safe train speed, and the levels of noise and vibration, as well as passenger comfort depend on the behaviour of ballast through particle interlocking and the corresponding deformation of this granular assembly. Attrition and breakage of ballast occur progressively under heavy and continual cyclic loading, causing track deterioration and rail misalignment affecting safety, while exacerbating the intensity of track maintenance. In the absence of realistic computational models, the track substructure is traditionally designed using mostly empirical approaches. In this book, the authors present the detailed information on the strength, deformation, and degradation aspects of fresh and recycled ballast under monotonic, cyclic, and impact loading using innovative geotechnical testing devices. A constitutive model for ballast incorporating particle breakage is presented representing a more realistic stress–strain response. The mathematical formulations and numerical models are validated using controlled experimental simulations and fully instrumented field trials. Revised ballast gradation is described to provide greater track resiliency and extended longevity. The book also provides a detailed description of geosynthetics for substructure improvement considering track deterioration caused by particle degradation, fouling, and impeded drainage. New to this second edition are extensive discussions on subgrade soil stabilisation, causes and mechanisms of soil fluidisation (mud pumping) under cyclic loading, and preventive and remedial measures to alleviate undue instability of ballast tracks. This book should prove most beneficial for final-year civil engineering students and for postgraduate teaching and learning. It is an ideal supplement for practising railway engineers and researchers engaged in the challenging tasks of future track design for heavier and faster trains.

Download or read book Track Data Oriented Maintenance Intervention Limit Determination for Ballasted Light Rail Tracks through Multibody Simulations written by David Camacho Alcocer and published by BoD – Books on Demand. This book was released on 2021-07-13 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light rail trains (LRT) are an important part of public transport but due to perceived high life-cycle costs are not always considered suitable. Life cycle cost reduction might be achieved through a knowledge-based maintenance management rather than just on experience. This work develops limits of maintenance and renewal of LRT systems based on vehicle reactions to the current track quality through measured data, multibody simulations and track geometry indices. An approach based on knowledge would lead to a track condition which allows a safe, comfortable, and under an appropriate maintenance strategy, economically profitable operation.
