It is considered how reliability of the grinding technology influences on the quality parameters of the treated surface. The results of analysis of relationship between quality of the rails grinding and conditions of its treatment are represented. Factors affecting on reliability of the technology are reviewed also. The model determining the reliability of the rails grinding technology in the railway is represented. Also the algorithm of calculation of the grinding technology reliability is represented. It’s reviewed how the quality parameters are formed during the rails grinding.

Article considers modern shumo-vibroprotective materials for car building. Security measure of the person from vibration in cars are constructive improvements, applica-tion of means of external vibroprotection by uprugodempfiruyushchy materials and devices which take place between a source of vibration and the person, and also continuous control of serviceabil-ity of cars and their timely scheduled preventive repair as in use and wear there is an expressed strengthening of vibration. Considering that constructional features of cars provide compliance "To health regulations on the organization of passenger traffic on railway transport" in the course of formation of structures and at operation of cars there are the technical problems caused by aging (technical wear) cars, a detsentrovka, defects of a way, etc. that leads in practice to deterioration of an acoustic mode of internal rooms of cars. Comparative researches of sound-absorbing properties of a material from aramide fiber and ecologically safe material NOL-1A(B) are conducted. Decrease in noise levels in rooms of cars, due to use of modern materials is experimentally established. NO-L-1A use in a design of air ducts of cars of locomotive draft allows to reduce considerably noise level in rooms, and to raise ecological characteristics of cars.

The article is devoted to finding ways to improve the maintenance of infrastructure. And suggested the expediency of refinement tools used methodology Urra, allowing significantly taken into account in the risk assessment process imperfect operation of the infrastructure associated with the influence of the «human factor».

The article examines the possibility of upgrading the existing control system of labor protection in relation to the used in the railway network methodology, resource management and risk management at all stages of the life cycle of facilities and equipment on the basis of reliability analysis (URRAN). Using practical examples, the possibility of using professional risk management system in the task of improving the safety of industrial processes and transport.

The article examines a possible approach to the construction of evaluation model of human influence on the functioning of human-machine systems. Formalization of procedures for the analysis of human influence in the «man - machine - environment» for their further integration into the risk management system is being implemented at JSC «Russian Railways» will improve the quality assessment and risk analysis, and, accordingly, to ensure the required level of security in rail transport.

Within the framework of the article, a study was made of the workplace of wheelchair washers for the purpose of determining the main occupational diseases and the causes of their occurrence. The theory of constructing rational modes of work and rest for working in the off-season in the open air is considered. The equation of integral index of cooling conditions is given. The risks associated with working in the cold are listed, as well as basic protection measures for workers, such as personal protective equipment and recommendations for restroom equipment. Within the framework of the article, the technological stages of manual washing of passenger carriages and a number of harmful production factors at the workplace of wheelchair washers are considered. In the process of analyzing the working conditions of the profession in question, a number of prof. diseases such as acute intoxication, dermatitis and dermatosis. The results of the conducted tests for the evaluation of the toxicity index and operational tests of samples of the detergent «Trans-Eco» with the aim of improving the working conditions of the passenger car wipers are presented.
