THE “HUMAN FACTOR” AND SAFETY PROBLEMS IN THE JOINT-STOCK COMPANY “RUSSIAN RAILWAYS” AS A FOUNDATION OF TRANSPORT BUSINESS IN XXI CENTURY

The paper concerns modern trends of the joint-stock company “Russian Railways” which involve in particular the growing importance of the human factor influence for safety on railway transport. A serious attention should therefore be paid to professional training along with physical and psychological reliability of personnel

ON THE ECONOMICAL SAFETY OF THE RAILWAY TRANSPORT PERFORMANCE

The paper is concerned with the problems of importance of transport in general, in particular, railway transport within the context of economical safety of the country. The negative tendencies taking place in the national transport branch, are revealed and analyzed. Finally, the economically justified recommendations for increase in investments into the railway transport are presented.

ON THE TECHNICAL APPROACH TO PURPOSEFUL MANAGEMENT OF ECONOMIC RESOURCES OF A TRANSPORT COMPANY

The paper is concerned with the problem of capital structure optimization through scenario option selection subject to criteria of profit maximization and minimization of costs and risks due to a delay in loan facility attraction. The spatial, time and spatial-time optimization of the capital structure allows to determine the optimal ratio of in-house and borrowed funds.

ON THE METHOD OF COSTS ESTIMATE DISCOUNTING

A new estimation method of exchange value for average and specialized objects is proposed in the paper. Depending on the character of the infobase used for initial data, the proposed method may be applied for costs estimate discounting or accounting costs discounting.

ON THE EFFICIENCY ENHANCEMENT OF AN UNDERCAR GENERATOR AT A LOW SPEED

It is well-known that the rolling stock electric supply system relies on a storage battery at a low speed (0-40 km/h). Taking into account that 50% of the train route corresponds to the speed of 15-25 km/h, the problem of nominal voltage generation at low speed becomes urgent. The traditional approach lies only within the field forcing.

ON THE DYNAMICS OF UNDISTURBED MOTION OF A LOCOMOTIVE TRUCK IN A CURVE OF A SMALL RADIUS

The paper is concerned with a problem of power imputs reduction for mounting the resistance occurring in the small radius curves passed by a locomotive truck and also a coupled problem of reducing the wearing level of the wheel flanges. The dependence relating the force of lateral pressure of the wheel flange on the rail and the variation of the longitudinal axe of a truck and the associated wheel pairs, is investigated.
