    Fixed Energy Storage Technology Applied for DC Electrified Railway

    IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, Issue 3 2010
    Takeshi Konishi Member
    Abstract The fixed energy storage system solves the problem of rising energy costs by reducing primary energy consumption. Without a fixed energy storage system, the energy generated by a braking vehicle would be simply converted into waste heat by its braking resistors if no other vehicles are powered simultaneously. Because, as a rule, such synchronized braking and powering cannot be coordinated, the energy storage system stores the energy generated during braking and discharges it again when a vehicle is powered. This greatly reduces primary energy demand in the substation. However, in addition to this energy saving, the energy storage system contributes to the reduction of CO2 emissions. The energy storage system also stabilizes the system voltage. Recent years have witnessed an advance in the energy storage media technology. Developments of energy storage media, lithium ion battery, nickel-metal hydride battery, and electric double-layer capacitors (EDLCs) have been remarkable. This study introduces technologies of fixed energy storage system applicable for DC electrified railway in Japan, and describes two examples of charge/discharge characteristics.

    An equity-based passenger flow control model with application to Hong Kong-Shenzhen border-crossing

    JOURNAL OF ADVANCED TRANSPORTATION, Issue 2 2002
    Hai Yang
    Cross-border passengers from Hong Kong to Shenzhen by the east Kowloon-Canton Railway (KCR) through the Lo Wu customs exceed nearly 200 thousand on a special day such as a day during the Chinese Spring Festival. Such heavy passenger demand often exceeds the processing and holding capacity of the Lo Wu customs for many hours a day. Thus, passengers must be metered off at all entrance stations along the KCR line through ticket rationing to restrain the number of passengers waiting at Lo Wu within its safe holding capacity. This paper proposes an optimal control strategy and model to deal with this passenger crowding and control problem. Because the maximum passenger checkout rate at Lo Wu is fixed, total passenger waiting time is not affected by the control strategy for given time-dependent arriving rates at each station. An equity-based control strategy is thus proposed to equalize the waiting times of passengers arriving at all stations at the same time. This equity is achieved through optimal allocation of the total quota of tickets to all entrance stations for each train service. The total ticket quota for each train service is determined such that the capacity constraint of the passenger queue at Lo Wu is satisfied. The control problem is formulated as a successive linear programming problem and demonstrated for the KCR system with partially simulated data. [source]

    The Fragmentation of a Railway: A Study of Organizational Change

    JOURNAL OF MANAGEMENT STUDIES, Issue 3 2005
    David Tyrrall
    abstract This paper considers pathways of organizational change within British Rail (BR) during its long period of commercialization culminating in privatization. The Laughlin (1991) and Parker (1995a) frameworks are used to demonstrate how a new interpretative scheme supplanted the previous interpretative scheme within BR between the 1970s and privatization in the mid-1990s, leading to a fragmented organization. BR did not survive and privatization of Britain's railways remains controversial. The study demonstrates that without the earlier changes in interpretive scheme from ,social railway' to ,business railway' to ,profitable business', and the associated changes in design archetypes and sub-systems, privatization would have been both less tempting and less feasible. It is intended that the approach developed here to analyse organizational change in BR should be applicable to the study of other privatizations and to other forms of organizational change in both the public and private sectors.

    A review of recent frozen soil engineering in permafrost regions along Qinghai-Tibet Highway, China

    PERMAFROST AND PERIGLACIAL PROCESSES, Issue 3 2002
    Wu Qingbai
    Abstract The nature of frozen soil research along the Qinghai-Tibet Highway between 1993 and 2000 is systemically reviewed. Recent studies involve the engineering geology of frozen soil, the study of ground temperatures under the roadbed and the influence of the frozen soil environment, the engineering classification of frozen soils, and the use of geographical information systems. This research will materially assist in the construction of the Qinghai-Tibet Railway. Copyright © 2002 John Wiley & Sons, Ltd. [source]

    Meßtechnische Erfassung von Lage und Verformung eines Stahltragwerks unter Temperatureinfluß

    BAUTECHNIK, Issue 2 2004
    Hans Schulz Dipl.-Ing.
    An einem Abschnitt des stählernen Traggerüsts der Wuppertaler Schwebebahn wurden über einen längeren Zeitraum dreidimensionale geodätische Messungen durchgeführt, um die Verformungen von Stahlbauwerken unter Temperaturlast zu untersuchen. Aus einem genauen geodätischen Netz heraus wurden die Koordinaten von am Objekt vermarkten Punkten bei gleichzeitiger Erfassung der Stahltemperatur bestimmt. Ziele der Untersuchungen waren, die mit einem Standardmeßverfahren in der Praxis erreichbaren Meßunsicherheiten für Kontroll-, Überwachungs- und Absteckungsvermessungen an komplexen Stahlkonstruktionen zu ermitteln und gleichzeitig zu überprüfen, ob sich die Konstruktion unter Temperaturlast dem Materialgesetz entsprechend verhält. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) Recording of position and deformation of a steel structure with geodetic measurements under varying climatic conditions. Repeated geodetic 3d-measurements on a part of the steel construction of the Wuppertal Suspension Railway were carried out to analyse the influence of the momentarily prevailing steel temperature on the geometry of the construction. Based on a precise geodetic network the coordinates of points marked out on the construction were determined simultaneously recording the steel temperature. The objectives of the measurement were on the one hand to derive the measuring uncertainties, that can be achieved in practice for control and setting-out measurements on complex steel constructions applying a standard method, and on the other hand to check if the behaviour of the construction under temperature load is according to the material's law.

    Thermal Characteristics of the Embankment with Crushed Rock Side Slope to Mitigate Thaw Settlement Hazards of the Qinghai-Tibet Railway

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 5 2009
    Guoyu LI
    Abstract: Permafrost (perennially frozen ground) appears widely in the Golmud-Lhasa section of the Qinghai-Tibet railway and is characterized by high ground temperature (,,1°C) and massive ground ice. Under the scenarios of global warming and human activity, the permafrost under the railway will gradually thaw and the massive ground ice will slowly melt, resulting in some thaw settlement hazards, which mainly include longitudinal and lateral cracks, and slope failure. The crushed rock layer has a thermal semiconductor effect under the periodic fluctuation of natural air. It can be used to lower the temperature of the underlying permafrost along the Qinghai-Tibet railway, and mitigate the thaw settlement hazards of the subgrade. In the present paper, the daily and annual changes in the thermal characteristics of the embankment with crushed rock side slope (ECRSS) were quantitatively simulated using the numerical method to study the cooling effect of the crushed rock layer and its mitigative ability. The results showed that the ECRSS absorbed some heat in the daytime in summer, but part of it was released at night, which accounted for approximately 20% of that absorbed. Within a year, it removed more heat from the railway subgrade in winter than that absorbed in summer. It can store approximately 20% of the "cold" energy in subgrade. Therefore, ECRSS is a better measure to mitigate thaw settlement hazards to the railway. [source]

    Permafrost Characteristics of the Qinghai-Tibet Plateau and Methods of Roadbed Construction of Railway

    ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 5 2008
    NIU Fujun
    Abstract Permafrost along the Qinghai-Tibet railway is featured by abundant ground ice and high ground temperature. Under the influence of climate warming and engineering activities, the permafrost is under degradation process. The main difficulty in railway roadbed construction is how to prevent thawing settlement caused by degradation of permafrost Therefore the proactively cooling methods based on controlling solar radiation, heat conductivity and heat convection were adopted instead of the traditional passive methods, which is simply increasing thermal resistance. The cooling methods used in the Qinghai-Tibet railway construction include sunshine-shielding roadbeds, crushed rock based roadbeds, roadbeds with rock revetments, duct-ventilated roadbeds, thermosyphon installed roadbeds and land bridges. The field monitored data show that the cooling methods are effective in protecting the underlying permafrost, the permafrost table was uplifted under the embankments and therefore the roadbed stability was guaranteed.

    Privatization in Canada: Operating and Stock Price Performance with International Comparisons

    CANADIAN JOURNAL OF ADMINISTRATIVE SCIENCES, Issue 2 2002
    Anthony E. Boardman
    This paper analyzes the operating and stock price performance of the major Canadian share-issue privatizations, including Air Canada, Canadian National Railway, Petro-Canada, and six provincial privatizations. First, using time-series accounting data, we examine changes in operating and financial performance before and after privatization. Second, we compare the Canadian performance experience to privatizations in other countries. Third, we examine the long-run effect of privatization on shareholder returns. The evidence indicates that privatization significantly improved the operating and financial performance of Canadian companies. Net income, profitability, efficiency, and dividend payments were significantly higher following privatization than before privatization. Employment and debt were significantly lower following privatization. Relative to privatizations in other industrialized countries, Canadian corporations did not grow as fast and had more layoffs. However, they experienced greater increases in profit and profitability, and larger reductions in debt. The increases in productivity, capital expenditures, and dividend payments were similar to firms in other countries. In the five years following privatization, shareholders of Canadian companies enjoyed significant, positive, market-adjusted buy-and-hold returns. This suggests that the operating performance improvements were larger than was expected at the time of privatization. Résumé Cette étude analyse les performances économiques et financières des sociétés d'État canadiennes qui ont été privatisées. En utilisant des données temporelles avant et après la privatisation, nous analysons trois entreprises privatisées par le gouvernement fédéral canadien (Air Canada, Pétro-Canada, et le Canadien National) ainsi que six autres entreprises privatisées par les gouvernements provinciaux. Nous comparons l'expérience canadienne aux autres privatisations majeures qui ont eu lieu à travers le monde. Finalement, nous étudions les rendements que ces entreprises ont procurés à leurs actionnaires. Les résultats tendent à démontrer qu'au Canada, la privatisation a eu un effet positif sur la performance. La rentabilité, la productivité, et les paiements de dividendes des entreprises canadiennes privatisées ont augmenté significativement suite à la privatisation. Le nombre d'employés et les niveaux d'endettement ont diminué de façon marquée. Comparativement aux privatisations mondiales, les privatisations canadiennes n'ont pas obtenu une croissance aussi grande et ont procédé à plus de mises à pied. Toutefois, on note une plus grande amélioration de la rentabilité et une plus grande réduction de l'endettement. Durant les cinq années qui ont suivi la privatisation, les actionnaires d'entreprises canadiennes privatisées ont bénéficié de rendements boursiers supérieurs à ceux procurés par l'ensemble du marché canadien de même que supérieurs à ceux procurés par les entreprises privatisées à travers le monde. Ce résultat tend à démontrer que l'amélioration de la performance des entreprises canadiennes privatisées a dépassé les attentes des investisseurs. [source]

    Comparing Investments in New Transport Infrastructure: Roads versus Railways?

    FISCAL STUDIES, Issue 3 2003
    Luisa Affuso
    Abstract This paper contributes to the debate on investment in transport infrastructure and the allocation of public funds between road and railway projects. We model the two options and provide a consistent framework to appraise investment in typical new inter,urban road and rail projects. Our results suggest that road improvements have substantially higher returns than railway schemes. These findings cast doubt on the rationale of the new transport policy for the UK, which proposes to allocate more public funds to the (private) railways than total new investment in strategic roads.

    The Use of Safety Suitability Tests for The Assessment of Immigrant and Majority Group Job Applicants

    INTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT, Issue 3 2004
    Jan Te Nijenhuis
    Safety jobs, meaning jobs where employees are responsible for the safety of customers, other employees and/or public in general are of special importance for our present society and deserve continued attention from I/O psychologists. The central question addressed in this study is whether the scores on safety suitability tests are comparable for immigrants and majority group members. Use was made of test data on first-generation immigrants (N=786) and majority group members (N=584) who applied for blue collar jobs at the Dutch Railways and at regional bus companies. The tests used measured selective attention, attentional speed, continuous attention, perceptual-motor ability and general mental ability. Immigrants' mean scores are systematically below the level of the mean scores of the majority group. The tests appear to have a strong dimensional comparability between the different groups. There is very little indication of test bias. The increasing number of immigrants and the increase of safety jobs pose challenges for selection psychologists. It is suggested that continued use of safety suitability tests is needed to keep the number of safety accidents at a minimum. [source]

    INTERNAL LABOUR MARKETS: EVIDENCE FROM TWO LARGE AUSTRALIAN EMPLOYERS

    AUSTRALIAN ECONOMIC HISTORY REVIEW, Issue 2 2009
    Andrew Seltzer
    Australian firms; banks; internal labour markets; railroads; salaries This paper examines internal labour markets in the late nineteenth and early twentieth century using personnel records from the Union Bank of Australia and the Victorian Railways. Both employers hired young workers and offered them the possibility of very-long-term employment. Salaries were determined by impersonal rules, such as being attached to tenure and to position. Workers rarely received nominal pay cuts. This approach to human resources was designed to retain and motivate workers. We show that all of the classic features of internal labour markets used to describe American firms in the 1970s were present dating back to the Victorian period. [source]
