  • Ballastless Track on High-Speed Lines a Guarantee for Travel Savety And
    Ballastless track on high-speed lines A guarantee for travel savety and comfort Prologue High–speed rail travel, as a fast connection between high-density population areas and as an alternative to frequently-overloaded air connections with an uncertain future, is gaining increasingly in significance all over the world. In the face of growing traffic density, critical views of life-cycle costs and significantly increa- sed requirements of the availability of railway tracks, there is an increasing demand for track systems which have a long lifetime, low service and maintenance costs and which also guarantee tra- vel safety and comfort. Ballastless tracks (BLT) have numerous advantages over the tradi- tional ballasted track, because of markedly reduced maintenance costs, longer duration of use, improved precision of the running track and the resultant quiet vehicle running. High speed and ballast The nature of the route requirements is changing, as a result of an increase in travel speed or axle loads. The load transported creates inertial forces and the particular more-frequent faults ari- sing from the rolling process are increasing dramatically. Altered deformation mechanisms with dynamic stimulation can result in major grain shifts during piling-up of ballast, which result in con- siderable impairment of the ballasted track and are responsible for uneven creeping and track displacement in the ballast bed. In addition, the track ballast stones are sucked up by vehicles at very high speeds (flying ballast) and may damage them. De- spite the choice of harder types of stone for ballast in high-speed traffic, maintenance costs are considerably higher.

  • New Design Concepts for High-Speed Lines and the Limits of the Ballasted Track Escobar, Adrián Zamorano, Clara Isabel Jiménez, Pablo Lorenzo Escobar, Jorge
    25 número 5 - junio - 2018. Pág 219 - 227 New design concepts for High-speed lines and the limits of the ballasted track Escobar, Adrián Zamorano, Clara Isabel Jiménez, Pablo Lorenzo Escobar, Jorge Technical University of Madrid1 Abstract The correct decision regarding to what type of track should be used in High-speed lines is one of the topics that has generated more discussion and controversy over the last few years. In addition, this decision is very influenced by the tradition, philosophy and design principles of the different countries. This fact is fundamentally due to the multitude of constraints and influencing factors that define as most appropriate, the use of a ballasted track against a ballastless track, or vice versa. However, the present research intends to look beyond and review the main High-speed projects of greater relevance and transcendence that are being or will be realized in the next years, around the world, to observe if some of the two typologies is presenting a greater implementation, and the main factors that are motivating this decision. In addition, the new conditions that are appearing in some countries will be analysed, related to the demand for greater performance of design speed and design life, as well as the influence that these new demands will have on the decisions related to the type of superstructure to be installed. Finally, a comparison of all these different design philosophies will be carried out, in relation to the Spanish High-speed model, in order to generate a brief discussion of the main differences and similarities found.

As of today, in case of conventional railway, there are 2 main types one could mention: ballasted and ballastless track solutions. However, there is no standardized procedure for choosing between these systems and between their respective variants, the decision is made on a case-by-case basis. This thesis aims to create a generic framework for decision making, primarily taking into account technical details. The model, the input parameters and variables can be easily adjusted and customized based on national standards, practices or other considerations, but the primary focus in the thesis have been the current Swedish regulations. The thesis has an overview on the influencing factors and attempts to include the most crucial ones of these into a decision-making model. This model compares 3 alternatives, namely the ballastless alternative, the ballasted alternative and the alternating system option, in which case the track system selection happens based on local factors, such as geotechnical conditions.

  • Developments in High-Speed Track Design
    DEVELOPMENTS IN HIGH-SPEED TRACK DESIGN Coenraad ESVELD Professor in Railway Engineering Delft University of Technology Delft, The Netherlands [email protected] Coenraad Esveld (1944), holds an MSc. and PhD degree in Civil Engineering and was ap- pointed professor of Railway Engineering at the Civil Engineering Faculty of Delft University of Technology (NL) in 1993 Summary Presently high-speed tracks are built on a large scale. Although ballasted tracks are still popular, more and more slab tracks are constructed. They have some significant advantages such as low maintenance, high availability, low structure height, and low weight. The main emphasis of this paper is on the application of non-ballasted concepts for high-speed operation. Special attention is given to slab soil interaction and optimization with respect to bearing capacity. Keywords: High-Speed Tracks, Slab Track Design, Slab-soil interaction 1 Introduction With the design of railway lines factors like life cycle cost, construction time, availability and du- rability play an increasingly important role. In this respect non-ballasted track concepts offer good opportunities. Especially with high-speed operation wave propagation under train velocity is an important factor, in particular in delta areas with relatively weak subgrades. This often makes it necessary to decide for slab track, as for instance was the case in The Netherlands for the High-speed Line South. With the growth of traffic intensity it becomes more and more difficult to carry out maintenance and re- newal work. In The Netherlands night time possessions often last no longer than 5 hours, and on the fu- ture high speed line in Korea (435 km from Seoul to Pusan) the maximum effective possession is estimated at no more than 1 ½ hours per night.

  • Development of the Countermeasure Against Roadbed Degradation
    Challenge H: For an even safer and more secure railway Development of the Countermeasure against Roadbed Degradation under Ballastless Tracks for Existing Lines Katsumi MURAMOTO, Takahisa NAKAMURA Track Structures and Geotechnology Laboratory, Railway Technical Research Institute, Tokyo, Japan Recently, ballastless tracks with cement grouted into ballast have been constructed on a full-scale construction operation in Japan Metropolitan Area. If the ballastless tracks are laid on clayey roadbeds, the soils are likely to be fluidized and flow out by trainloads. Consequently, track degradations typified by a large track depression sometimes occur. In this study, the authors carried out the test with a full-scale ballastless track model laid on a saturated clayey roadbed. From the results of the test, it was confirmed that degradation of the ballastless track on a clayey roadbed is caused by local progressive failure; specifically, the outflow of the fine-grain fraction in roadbed surface. In addition, the authors confirmed that the BLITS (Bentonite Liner for Track-bed Surface) method is one of the reasonable countermeasures for the roadbed degradation under the ballastless tracks. Keywords: roadbed, ballastless track, roadbed degradation, mud pumping, bentonite 1. Introduction When ballastless tracks (Fig. 1) are constructed on sound roadbeds, the maintenance work and the maintenance costs become generally less than conventional ballast tracks. However, if the ballastless tracks are laid on clayey roadbeds, the soils are likely to be fluidized and flow out by the trainload. Consequently, track degradations typified by a large track depression sometimes occur. The authors, therefore, have carried out moving-load tests with small-scale ballastless track models on clayey roadbeds and reappearance tests of the roadbed degradation using small-scale cylindrical molds, so that the basic defect mechanism of clayey roadbeds has been clarified (Fig.

This paper uses a life cycle assessment (LCA) method and a life cycle cost (LCC) analysis method to summarize the energy consumption, carbon emissions and costs of the Beijing-Shanghai HSR from the perspective of life cycle, and proposes some corresponding suggestions based on the results. The research objective of this paper is to analyse the carbon emissions, energy consumption, and costs of the rail system which includes the structure of the track and earthwork of the Beijing-Shanghai HSR during four stages: conception stage, construction stage, operation and maintenance stage, and disposal stage. It is concluded that the majority of the carbon emissions and energy consumption of the entire rail system are from the construction stage, accounting for 64.86% and 54.31% respectively. It is followed by the operation and maintenance stage with 31.60% and 35.32% respectively. In contrast, the amount of carbon emissions and energy consumption from the conception stage is too small to be considered.
