Indian Railways in the Past Twenty Years Issues, Performance and Challenges

Indian Railways (IR) is Asia’s largest and world’s second largest network under one management, with a separate Ministry and its own annual budget. The network carried about 17 million Passengers and 2 mt freight every day on the route of 63,327 km (2006-07). Although key business operations are freight and passenger, IR is also engaged in several allied services including parcel, catering and production units. Nearly 70 percent of IR’s revenues come from the freight operations, which can be segmented into bulk and other cargo. Over the years, IR has predominantly become a bulk freight carrier, accounting for about 94 percent of the freight revenue. Coal alone accounts for nearly half of the bulk traffic carried. Passenger business accounts for nearly 60 percent of IR’s total transport effort, in terms of train kilometers, but yield less than 30 percent of the total revenues. Suburban services account for 57 percent of the originating passengers, while contribute to only 8 percent of the passenger revenue. To understand the development process of IR’s over the past twenty years, the study covers issues and strategies related to financial and physical aspects of revenue generating freight and passenger traffic from 1987-2007. Study also covers the developments in the parcel, catering and advertising sector.

Overview of Infrastructure Charging, part 4, IMPROVERAIL Project Deliverable 9, “Improved Data Background to Support Current and Future Infrastructure Charging Systems”

Improverail aims are to further support the establishment of railway infrastructure management in accordance with Directive 91/440, as well as the new railway infrastructure directives, by developing the necessary tools for modelling the management of railway infrastructure; by evaluating improved methods for capacity and resources management, which allow the improvement of the Life Cycle Costs (LCC) calculating methods, including elements related to vehicle - infrastructure interaction and external costs; and by improving data background in support of charging for use of railway infrastructure. To achieve these objectives, Improverail is organised along 8 workpackages, with specific objectives, responding to the requirements of the task 2.2.1/10 of the 2nd call made in the 5th RTD Framework Programme in December 1999.This part is the task 7.1 (Review of infrastructure charging systems) to the workpackage 7 (Analysis of the relation between infrastructure cost variation and diversity of infrastructure charging systems).Before explaining the economic characteristics of railway and his basic pricing principles, authors must specify the objectives of railways infrastructure charging.principle of pricing ; rail infrastructure charging ; public service obligation ; rail charging practice ; Europe ; Improverail

Infrastructure Design, Signalling and Security in Railway

Railway transportation has become one of the main technological advances of our society. Since the first railway used to carry coal from a mine in Shropshire (England, 1600), a lot of efforts have been made to improve this transportation concept. One of its milestones was the invention and development of the steam locomotive, but commercial rail travels became practical two hundred years later. From these first attempts, railway infrastructures, signalling and security have evolved and become more complex than those performed in its earlier stages. This book will provide readers a comprehensive technical guide, covering these topics and presenting a brief overview of selected railway systems in the world. The objective of the book is to serve as a valuable reference for students, educators, scientists, faculty members, researchers, and engineers

Optimal Control of Hybrid Systems and Renewable Energies

This book is a collection of papers covering various aspects of the optimal control of power and energy production from renewable resources (wind, PV, biomass, hydrogen, etc.). In particular, attention is focused both on the optimal control of new technologies and on their integration in buildings, microgrids, and energy markets. The examples presented in this book are among the most promising technologies for satisfying an increasing share of thermal and electrical demands with renewable sources: from solar cooling plants to offshore wind generation; hybrid plants, combining traditional and renewable sources, are also considered, as well as traditional and innovative storage systems. Innovative solutions for transportation systems are also explored for both railway infrastructures and advanced light rail vehicles. The optimization and control of new solutions for the power network are addressed in detail: specifically, special attention is paid to microgrids as new paradigms for distribution networks, but also in other applications (e.g., shipboards). Finally, optimization and simulation models within SCADA and energy management systems are considered. This book is intended for engineers, researchers, and practitioners that work in the field of energy, smart grid, renewable resources, and their optimization and control

Méthodologie pour lídentification des fonctions potentielles dans la réutilisation des bâtiments vacants du patrimoine industriel. Etude des cas: les industries de long de la Rivière Almendares, La Havane

The problematic of the reuse of vacant industrial building is a topic relevant for the current society. It lays its regard over the vacant industrial heritage building looking for a possibility of recuperation or repurpose of their spaces. Though the number of examples overtakes the capacity of the decision markers. This together with a lack of tools for the definition of new function leave the spaces to interventions that no always correspond with the context and the object. Nevertheless, there is a large path already done in term of reuse of vacant industrial buildings. Some authors characterize this as a culture of the exploitation. This scenario is also present in Havana, Cuba. There is a vast representation of vacant industrial heritage buildings not correct exploited according their capacities. In this frame, the thesis is supported on the determination of a methodology for the identification of potential uses for the vacant industrial heritage building, taking as a relevant resource, the experience gained in the world in term of reuse that could be applied to the case of the industrial building along the Almendares River. The research is divided in three chapters, the first concerning to the identification of the variables that model the problematic, the second focus in the learning by the experience and the design of the methodology and the third in the application of this methodology to the study case of the vacant industrial heritage buildings along the Almendares River of Havana. The application to the study case serves from the test of pertinence of the methodology. The thesis has as result the Methodology for identification of potential use for vacant industrial heritage building, a database of experience of reuse and a proposal of potential use to be applied in the case of the Almendares River; Résumé: La problématique de la réutilisation des bâtiments industriels vacants est un sujet pertinent pour la société actuelle, qui fixe son regard sur le bâtiment du patrimoine industriel vacant à la recherche d'une possibilité de récupération ou reproposé de leurs espaces. Cependant, le nombre d'exemples dépasse la capacité des décideurs. Ceci, combiné avec un manque d'outils pour la définition d'une nouvelle fonction, laisse les espaces pour les interventions qui ne correspondent toujours avec le contexte et l'objet. Néanmoins, il y a un grand chemin déjà fait en question de réutilisation des bâtiments industriels vacants. Certains auteurs qualifient cela comme une culture de l'exploitation. Ce scénario est également présent à La Havane, Cuba. Il y a une vaste représentation des bâtiments vacants du patrimoine industriel qui ne sont pas exploitées de manière adéquate selon leurs capacités. Dans ce cadre, la thèse est soutenue sur la détermination d'une méthodologie pour l'identification des utilisations potentielles pour le bâtiment industriel vacant du patrimoine, en prenant comme une ressource pertinente, des expériences acquises dans le monde en questions de réutilisation qui pourrait être appliquée au cas du bâtiment industriel le long de la rivière Almendares. La recherche est divisée en trois chapitres, le premier concernant à l'identification des variables qui modélisent la problématique, le deuxième dans l'apprentissage par l'expérience et la conception de la méthodologie et la troisième a l'application de cette méthodologie à l'étude de cas de les bâtiments industriel vacants de patrimoine le long de la rivière Almendares de la Havane. L'application à l'étude de cas permet pour le test de pertinence de la méthodologie. La thèse a pour résultat la méthodologie pour l'identification des utilisations potentielles pour vacants bâtiment industriel du patrimoine, une base de données de l'expérience de la réutilisation et une proposition des utilisations potentielles à appliquer dans le cas de la rivière Almendares

Efficient multiscale methodology for local stress analysis of metallic railway bridges based on modal superposition principles

This paper presents an advanced submodelling methodology for local stress analysis of complex details of existing metallic railway bridges. The fatigue assessment of connections of large structures based on local methods leads inherently to a multiscale problem that can only be solved by adopting efficient numerical procedures. Aiming to overcome such limitations that influence the analysis process, submodelling techniques and modal superposition principles are combined to fully represent numerically the local geometrical, material and contact properties of the fatigue-critical details. The results of experimental in situ tests are proposed to characterise the numerical models and respective multiscale relation, implementing optimisation and validation procedures. In this work, the suggested efficient multiscale methodology for stress analysis aims to allow the subsequent local fatigue assessment, according to the real mechanism of loading transference, reducing sources of conservatism. All numerical procedures and respective validation thru experimental techniques are illustrated using a real case study.This work was financially supported by: Base Funding - UIDB/04708/2020 of the CONSTRUCT - Institute of R&D In Structures and Construction - funded by national funds through the FCT/MCTES (PIDDAC) and by national funds through FCT - Fundação para a Ciência e a Tecnologia; PD/BD/114101/2015.

Control Strategies and Design to Range in Light Railway Systems

The thesis deals with different control strategies and a design method to improve energy efficiency and reliability in light railway transportation systems. The possibility of use Supercapacitors Energy Storage System (SESS) in light railway systems is explored, by evaluating the suitability of on-board application for a Prototype Railway Vehicle, with the introduction of a methodology for Design to Range in catenary free operations in order to fill gaps in power supply. Furthermore, a stationary configuration of SESS in light railway system is also investigated by means of a demonstrator of a Metro rail System set in Hitachi Rail Italy test room, carrying out a control strategy for energy flows management in case of non receptive DC grid. Further investigations has regarded the introduction of two sensorless control strategies for two different railway traction architectures with IM and PMSM drives, focusing the attention on energetic and dynamic performance in different specific operating conditions required to the railway traction drives. Numerical and experimental results are obtained and discussed in different operating conditions, for real case studies, showing the feasibility and the fulfillment of the mission for the different solutions proposed
