Abstract (sommario):

The main goal of this work is the evaluation of the energy saving achievable in railway drive when using the coasting technique extensively, with reference to a practical case of the Italian railway network taken as an example. This technique consists in exploiting the kinetic energy accumulated by the running train whenever possible. To implement a driving style on purpose, the only driver contribution is not enough; indeed, it is necessary to provide an embedded automatic calculation control system. In the paper, an algorithm has been developed to evaluate the energy absorption of railway locomotives during the normal service and validated on a real railway line. The proposed hardware and software system could be implemented aboard the train, allowing motion data processing in real-time. Speed, time intervals and power absorption for a given path are calculated; then, the best coasting parameters are estimated to maximize the energy savings. In particular, the case study presented in the paper showed that the fast-run strategy, always adopted by the railway company to recover an unexpected delay, can lead to a negligible time recovery with respect to the coasting strategy, while determining a significantly larger energy consumption.

Abstract (sommario):

To fulfill the demand for a number of railroad products, the national railroad industry, in this case PT. INKA as a train integrator industry in Indonesia still has to import components. TKDN electric train is still low. For this reason, it is time to prepare the industrial development of the national railway propulsion system components and even have a very urgent nature. Railway propulsion systems can be classified into three groups, namely: Electric propulsion systems, Diesel Electric propulsion systems and Diesel Hydraulic propulsion systems. Import dependence, of course, cannot be allowed to continue because it will weaken the competitiveness of the national railroad industry. From the results of the analysis using the "Porter Diamond Condition" method various internal and external factors were identified through the SWOT method to formulate alternative policy formulations for the development of the railroad electric propulsion system industry in Indonesia. Qualitative SWOT data are developed quantitatively through the calculation of SWOT Analysis so that the exact position of the organization is known. From the results of the analysis, and calculations using the SWOT Method, the position of the railway propulation system industry is in the Quadrant IV position, so it is best to use a Defensive Strategy. In this position the Company faces a very unfavorable situation, the company faces various threats and internal weaknesses. For this reason, it is necessary to prioritize strengthening strategies in the Matrix (W-T). Key Words: Electric propulsion; Industrial development; Strategy

This study aims to demonstrate the significance of assessing corporate success in terms of economic value added (EVA). Economic value added is widely recognized as a reliable metric for assessing the performance of private firms. Four organizations were chosen, and their performance was assessed using the EVA approach from 2016 through 2022. The following outcomes were found as a consequence of the analysis: National Electric Company (NEC), Congo National Railway Company (NRCC), and Port Transportation Company (CCPT). A positive EVA, on the other hand, represents value creation for a Water Distribution Company (WDC). Endogenous variables such as the steady fall in factor returns to labor, poor operating performance, and low capital profitability cause value destruction. Yet, ethics and openness are essential for attaining success. Corporate success in terms of economic value added (EVA).

Abstract (sommario):

Increasing the efficiency of cargo transportation by rail is not only one of the main directions of the company JSC “Russian Railways” but also one of the main tasks of our country in order to achieve sustainable economic growth. Electric rolling stock is the largest consumer of electric energy in the company, that’s why its effective and failure-free operation is the way to solve the set tasks. The paper deals with studies related to the operation modes of a freight electric rolling stock of direct current for the purpose of determining the requirements for electric energy storage device, since it is the electric rolling stock that determines the daily schedule of electric load. The order of the analysis of experimental trips of freight electric locomotives of a direct current on the basis of cartridges of recorders of traffic parameters installed on the locomotive is determined. On the basis of the analysis of conducted trips, the main requirements for the energy storage device were obtained with a single running of electric DC rolling stock, namely the average duration of the operation modes of the electric locomotive, the maximum, minimum, and average values of voltage and current, the average value of the electric energy returned to the contact network, time of charge/discharge, and the useful energy intensity of the electric energy storage device. The studies were carried out with the support of the Russian Foundation for Basic Research for the project No 17-20-01148 ofi_m_RZD/17.

Abstract (sommario):

Stocks and bonds issued by industrial companies listed and traded on the stock exchange belong to industrial stocks. For example: electric power, steel, automobile, food, beverage, wine, textile, pharmaceutical, and other enterprises engaged in product manufacturing stocks, bonds and other securities. In the United States, industrial stocks make up a large proportion of the economy. In the process, investors can make a lot of profits. Despite more than a century of growth in such industries, there is still a lot of potential. Industrial stocks are among the areas with the longest shelf life in the United States and the world. This paper analyses the selected three companies in industrial sector the three aspects of risk, profitability and market ratio to predict basic trend in this area. Three companies are Canadian National Railway Company (CNI), Caterpillar Inc. (CAT), FedEx Corporation (FDX). The results show Canadian National Railway Company is less risky and FedEx Corporation is least profitable. The findings in this paper may benefit the different investors in financial markets on investment decisions.

Abstract (sommario):

The article provides a retrospective analysis of the historical experience and problems of corporatization of the Dnipropetrovsk electric locomotive plant – a leading domestic manufacturer of industrial electric vehicles and railway rolling stock. The author traces historical circumstances of development and preconditions of diversification of production activity of the enterprise on the background of market economy in Ukraine and decrease in demand for narrowly specialized products. It was found out that during the 1990s–2000s the staff of SPA «DEVZ», having a promising research and production potential, mastered a wide range of production of mainline equipment to meet the needs of railways for innovative electric vehicles. However, due to low product quality and inefficient management system, the company is currently on the verge of bankruptcy, and its outdated design and technological improvements are not able to ensure competitiveness in the global railway market. It is proved that given the strategic importance of SE «DEVZ» for the national economy as the last profile locomotive company, its corporatization can be a real alternative to privatization, providing effective capitalization, financial and technological recovery and improving the culture of production with a state guarantee of preservation of the enterprise, as well as obtaining additional funds through the placement of securities on stock exchanges, and attracting private investment and innovation from international manufacturers. Further research on the historical aspects of the development of domestic engineering enterprises and their impact on the fleet of JSC «Ukrzaliznytsia» should be carried out taking into account the achievements of domestic science on the problems of structural adjustment of the economy and the use of modern strategic management tools.

Abstract (sommario):

Regional cooperation in rail transport can help participating countries diversify their trade patterns. Improved rail transport can also help attract foreign direct investment, increase participation in global production networks and the scale of related trade in manufactured goods, and diversify exports. Improved rail infrastructure will increase global competitiveness and spur economic development. In addition, improved rail infrastructure will help regional cooperation and integration through improved connectivity between people, goods and services. The operation is carried out by a railway company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway electrification system or produce their own power, usually by diesel engines or, historically, steam engines. Most tracks are accompanied by a signalling system. Railways are a safe land transport system when compared to other forms of transport. Railway transport is capable of high levels of passenger and cargo utilisation and energy efficiency but is often less flexible and more capital-intensive than road transport, when lower traffic levels are considered. Railways are a climate-smart and efficient way to move people and freight. Keywords: railway, transport, improvement, transportation, transit, passenger, development, delivery, traffic, technology, vehicles.

Abstract (sommario):

Abstract For many years the most advanced railway propulsion systems have been based on the use of electric motors. Compared to the other available solutions, these are characterized by greater operating economy and less environmental pollution. In order to operate as efficiently as possible and to guarantee the high standards of electromechanical reliability, these propulsion technologies need adequate cooling systems to operate in controlled temperature conditions. Considering this, the implementation of increasingly accurate and performing simulation models can represent a significant advantage and provide great support in the optimization phase of cooling systems, in terms of reduction of dimensions and weight, rapid and low-cost experimentation, prediction of critical scenarios and choice of the best solution strategies to be taken. In this regard, in the context of the collaboration between the University of Naples Federico II, University of Sannio and the company Hitachi Rail STS S.p.A., several lumped parameter models of power converter cooling systems for railway electric propulsion were developed in the Simcenter AMESim environment. These models allowed to validate specific design choices from thermal and hydraulic perspectives, aimed at higher energy efficiency of the system, and to perform the so-called Last Mile predictive analysis, in order to evaluate the possibility of removing a vehicle from the railway line as consequence of a fault of specific components.

Abstract (sommario):

Purpose The purpose of this paper is to present the results of the application of various models to estimate the reliability in railway repairable systems. Design/methodology/approach The methodology proposed by the International Electrotechnical Commission (IEC), using homogeneous Poisson process (HPP) and non-homogeneous Poisson process (NHPP) models, is adopted. Additionally, renewal process (RP) models, not covered by the IEC, are used, with a complementary analysis to characterize the failure intensity thereby obtained. Findings The findings show the impact of the recurrent failures in the times between failures (TBF) for rejection of the HPP and NHPP models. For systems not exhibiting a trend, RP models are presented, with TBF described by three-parameter lognormal or generalized logistic distributions, together with a methodology for generating clusters. Research limitations/implications For those systems that do not exhibit a trend, TBF is assumed to be independent and identically distributed (i.i.d.), and therefore, RP models of “perfect repair” have to be used. Practical implications Maintenance managers must refocus their efforts to study the reliability of individual repairable systems and their recurrent failures, instead of collections, in order to customize maintenance to the needs of each system. Originality/value The stochastic process models were applied for the first time to electric traction systems in 23 trains and to 40 escalators with ten years of operating data in a railway company. A practical application of the IEC models is presented for the first time.

Abstract (sommario):

This thesis examines the introduction of electric household appliances in Victoria, British Columbia between the world wars. As of 1919, electric lighting had already replaced gas, but electric appliances were still uncommon. Expensive to buy and use, their diffusion was further retarded by poor household wiring standards and uneven service from the monopoly utility, the British Columbia Electric Railway Company (BCER). This firm at first showed little interest in developing the domestic market. However, problems with industrial and corporate customers showed that household customers provided more stable and reliable revenues. Simultaneously, time payments, standardized electrical outlets, and improved wiring standards made its service more attractive to Victoria's consumers. Even so, the BCER remained cautious in developing this market though, maintaining high rates and at first discouraging the spread of electric ranges, as these intensified peak demand. Overall, one does not find a patriarchal, manipulative corporation imposing appliances on Victorians. Consumers, women in particular, were more autonomous than most scholars suggest. Electrical capitalists trailed behind rather than led demand.

Abstract I have lost count of the number of times I have visited Gettysburg. Over the past forty years I have walked, bicycled, and driven around the battlefield and town by myselt with a few friends, and with groups as large as a hundred. I honestly believe that if I were blindfolded and winched down to any spot on the battlefield from a helicopter on a cloudy night, I could remove the blindfold and identif)’ my surroundings within seconds. Gettysburg has come to have a special place in my consciousness, just as it has acquired an unequaled place in the American historical consciousness. When Congress created Gettysburg National Military Park in the 1890s, the Gettysburg Electric Railway Company owned part of the land on which the battle had been fought. The GERC had begun moving earth to build a trolley line to carry tourists over the battlefield.

Abstract (sommario):

The purpose of the study. To examine how the 19th century economic modernisation (Western type of industrialisation, technological transformation and the birth of the manufacturing industry) unfolded in Central Europe; and more importantly in Hungary, at Pécs, and what technological innovations were created by local entrepreneurs. Applied methods. Literature review including the history of the manufacturing industry. We involved sources from monographies, employment and census records, reminiscences and our own data from researches of archives. The research framework is the history of distinct businesses. We introduced five businesses whose economic effects influenced the operations of Pécs in the long run. We made a structural analysis examining the entrepreneur and its business together. Outcomes. The Austrian First-Danube-Steamboat-Shipping Company (DDSG) became the largest works in the city by starting intensive coal mining and creating modern technological background since 1852. It employed four thousand souls at the beginning of the 20th century and the city profited a lot from its developments (railway construction and electric power plant). The Zsolnay Porcelain Manufactory quickly became the synonym of Pécs. Vilmos Zsolnay ended up being a world famous entrepreneur because of his technological innovations (eosin, pyrogranite, etc…) and products. The term “Glove of Pécs” came alive in the ages of the dual monarchy. János Hamerli founded the first glove manufacturing plant in the country. The Angster Organs have played for hundred and fifty years. The company founded by József Angster emerged at the end of the 19th century and represented state of art technology.

Abstract (sommario):

Norfolk Southern Railway Company (NS) is developing an all-electric switching locomotive, the NS 999, to provide a zero point source emission electric locomotive option for rail switching service. The original NS 999, unveiled in September 2009, suffered from poor battery management and challenging battery packaging. The rebuilt NS 999, anticipated in the 4th quarter 2013, will be powered by Axion Power’s PbC® batteries. The Axion PbC® batteries provide increased charge/discharge cycle life and charge acceptance compared to conventional Valve Regulated Lead–Acid (VRLA) batteries, as well as increased usable energy when configured in series as ‘long strings.’ NS and Axion will review the challenges of the initial NS 999 battery management system, improvements to the battery management system, and test results from the Norfolk Southern Hybrid Locomotive Simulator using Axion’s PbC® lead–carbon hybrid battery/supercapacitor. Axion will present test data showing the low variation in strings of PbC® batteries compared to VRLA while simulating locomotive switching. PbC® batteries have a unique charging curve, known as “concave down, increasing,” which allows the batteries to self-equalize in strings. This characteristic of PbC® batteries provides for simpler battery management and reduced maintenance charging, while increasing the usable energy available within the string. The rebuilt experimental locomotive NS 999 will use Axion’s PbC® lead–carbon batteries for the energy storage system to power locomotive switching and recover braking energy. If this research is successful, a zero point source emission electric locomotive could provide an option to reduce emissions in urban non-attainment areas and reduce dependence on petroleum. The NS 999 electric switcher is the first step to the ultimate goal of recovering braking energy from high power conventional diesel locomotives.

Abstract (sommario):

For the near future business application, the new idea of the distributed energy network system is proposed to secure lower cost and highly reliable power and heat supply system for the limited local area such as high energy density urban area. In Japan, tariff of the electric power is same for urban consumers and rural consumers under the present power law. However the wave of the power deregulation may affect to small business users and home users and the free-market of power purchase may emerge in public domain. Towards the realization of the future active power market, the new idea is created to promote the intelligent distributed power generation systems and heat utilization systems using the Internet application and local energy network construction. This system has been discussed in the consortium, consisting of Nagoya University, Gas Company, Power utility, Trade Company, IT Company etc since May 2000. The idea of the proposed eL-power network system is to supply necessary power and heat to the only customers in the high energy density area like near the railway station using energy management by mean of the Internet technologies.

Abstract (sommario):

Russian power generation, oil and gas businesses are rapidly growing. Installation of new industrial gas turbines is booming to fulfill the demand from economic growth. Russia is a unique country from the annual temperature variation point of view. Some regions may reach up to 100C. One of the biggest challenges for world producers of gas turbines in Russia is the ability to operate products at power plants during cold winters, when ambient temperature might be −60C for a couple of weeks in a row. The reliability and availability of the equipment during the cold season is very critical. Design of inlet systems and filter houses for the Russian market, specifically for northern regions, has a lot of specifics and engineering challenges. Joint Stock Company CKTI is the biggest Russian supplier of air intake systems for industrial gas turbines and axial-flow compressors. In 1969 this enterprise designed and installed the first inlet for the power plant Dagskaya GRES (State Regional Electric Power Plant) with the first 100MW gas-turbine which was designed and manufactured by LMZ. Since the late 1960s CKTI has designed and manufactured inlet systems for the world market and been the main supplier for the Russian market. During the last two years CKTI has designed inlet systems for a broad variety of gas turbine engines ranging from 24MW up to 110MW turbines which are used for power generation and as a mechanical drive for the oil and gas industry. CKTI inlet systems with filtering devices or houses are successfully used in different climate zones including the world’s coldest city Yakutsk and hot Nigeria. CKTI has established CTQs (Critical to quality) and requirements for industrial gas turbine inlet systems which will be installed in Russia in different climate zones for all types of energy installations. The last NPI project of the inlet system, including a nonstandard layout, was done for a small gas-turbine engine which is installed on a railway cart. This arrangement is designed to clean railway lines with the exhaust jet in a quarry during the winter. The design of the inlet system with efficient multistage compressor extraction for deicing, dust and snow resistance has an interesting solution. The detailed description of challenges, weather requirements, calculations, losses, and design methodologies to qualify the system for tough requirements, are described in the paper.
