The History, Present and Future of the Railway Research

The railway research, development and testing considerably contribute to the advancement of mobility of both people and goods in Europe. In the beginning of railways, the research gained recognition for the preparation of research and development methods in general, recently the research performs tasks which are important for success of railways on the free transport market. The Czech railway research was successful in these activities and strives after being successful also in the future. The Railway Research Institute of Prague, being a representative of the railway research and testing, maintains the long tradition, human resources, apparatus and testing background and cooperates with railways and industries all over the Europe. Its qualification for certification tests and experiments for research works is demonstrated by EN 45 000 certificate and licenses granted by national certification authorities - see enclosed documents.

Contribution of the Railway Research Institute for the Development of Electrical Engineering and Power Engineering in Rail Transport

The paper is a collective work of authors who all have spent many years in the branch of railway and railway research. They specialize on railway electrical engineering, as applied both in rail vehicles or stable devices designed for the railway transport. Therefore, the paper both describes a general history of the electrical engineering penetrating into the railway transport and gives a survey of basic works and activities in the past fifty years in the institution the name of which was subject to numerous modifications, but always maintained the word research. ”Electrical Engineering Research” had been one of five working sections of the first ČSD Research and Testing Institute founded in 1950 and still forms its integral part. The seat of the official electrical engineering research of railway - ČSD had not always been only in Prague, the capital of VÚŽ electrical engineers had been for twenty years the town of Vrútky, Slovakia, a town with important and long railway history. The paper presents information about works and their results regardless of the places of their origin providing that such places were any VÚŽ site. The paper follows both a time line and material classification. The paper stresses the contribution of research in the electrification of lines at first using the DC 3kV traction system, later on AV 25kV, 50Hz system. A chapter dealing with locomotives with controlled converters follows. Otherwise, electric locomotives are mentioned throughout the text. A short mention of semi-conductor converters is also included, which converters replaced rotation ones for the power supply of railway security devices. A separate chapter deals with the subject of power savings, especially in connection with issues of energy-optimal train running. The final chapter deals with activities of VÚŽ electrical engineers in another type of track transport - Prague subway, where their knowledge and experience were used both in the development and tests of cars and power supply system. Tens, maybe hundreds of research tasks in the field of railway electrical engineering are represented in the paper by a description of the most important moments of some of them, which have impacted, due to different reasons, the authors' memory more than the others.

Technical Development of Railway Constructions and Structures in the Process of Advancement of Rail Transport

In addition to the general process of development of the "large" building industry which is employed also in railways especially in the form of construction and maintenance of buildings and artificial structures, the specific research and development appeared in the past fifty years which were aimed not only at specialized branches of the railway substructure, superstructure, long-welded rails, technique and mechanization of line construction and maintenance including checks and measurements, but also at the application of technical advancement of related branches. These include, for example, special railway geodesy and cartography or recently the ever more intensive application of environmental aspects, computing and information technology, etc. The paper mentions not only the most significant results of the technical development of major specialized fields from the W.W.II until the nineties, but also stresses those research and development results which were implemented in manufacturing or operation organizations.

Contribution of the Railway Research Institute for the Development of Rail Transport in the Communication and Security Technology

The paper briefly mentions the circumstances under which the field of VÚŽ communication and security technology had been formed, had worked and has been working. Certain specific features are due to that the field of security technology is a branch with its considerably own philosophy focused on the safety of transport, persons and goods. Work in this branch naturally demands long years of both professional and life experience. The paper also very briefly lists the results of works, especially of the works which have been broadly applied in the practice. Workers achieved in their implementation valuable experience which enable them providing they have necessary conditions, to solve in a qualified manner other important and necessary tasks. The field of communication and security technology had also been subjected to the staff reduction. In spite of leaving of, frequently top-quality, employees who were hardly replaceable in a short time, the situation has stabilized and the Institute has maintained its ability to continue its proactive approach to the improvement of railway equipment in cooperation with both national and foreign partners. The following should be pursued and supported: development of knowledge in the field of new techniques and their application in domestic security systems, research of general compatibility of communication and security systems, research and application in the field of means for train detection, complex protection of communication and security devices against unauthorized effects, development of efficient diagnostics and rational maintenance of all systems, including systems with new techniques, development of formal methods for the preparation of specifications, modeling, testing and verification of security systems.
