Purpose. Scientific paper is aimed at disclosing the existing problem of the «reliability» definition and provides a reasoned definition of the term. The study assumes the development of a complex that includes the methodology and appropriate terminology that will be true. Methodology. Currently there is reliability theory in the special case of the probabilistic and statistical theory, which is used to determine or predict the occurrence of object failures. Within the existing theories the term «reliability» is formulated, the parameters related to it are described. Findings. On the basis of the conducted analysis of the research within the existing theory of reliability and personal considerations of the authors, they formulated a definition of the term «reliability». The methodology and study of the object reliability on the example of a freight car was proposed. Originality. The authors proposed a new definition of the «reliability» term. Namely: reliability is an assessment of the ability of an object to maintain the original property within the established limits and temporary space, in the conditions of storage and transportation, as well as to perform the required functions in predetermined modes of operation with maintenance and repair facility. The reliability parameters include: reliability, durability, maintainability and safety that characterize the object. Also a methodology for developing and study the reliability of a freight car was developed, which comprises: 1) design, technological and operational reliability; 2) scientific experiment, including the modeling of the freight car in different conditions and operating modes; 3) the reliability theory is presented as combined or modified, covering the mathematical and physical foundations; 4) Bayesian statistics that describe the different states of a freight car with a breakdown of its basic components and with the appropriate probability for each component to describe the overall reliability. Practical value. The results of the study allow to provide a full and accurate picture with a corresponding failure of a freight car and to improve approaches to the construction and study of the reliability of the car overall.
