Abstract

The work is dedicated to the substantiation of design schemes of platform-cars for the organization of road-trains and wheel engineering transportation by railway. In the paper the analysis presented of rolling-stock designs for the organization of road-train and wheel equipment transportation, legislation requirements, a standard legislation for designing rolling-stock, requirements of transport operators and a logistic infrastructure existing in the country allowed formulating criteria for the choice of an efficient design scheme of a platform-car. 
 In accordance with the criteria accepted there are offered three versions for the design of cars. In the first two versions of platform-cars there is foreseen a lower stationary platform on a based length. The difference of the second version consists in the application of a bearing element in a truss structure as a basic one. For both designs there are obtained utility patents. The third version provides for the presence of a load lifting platform. For the substantiation of an efficient design of a platform-car there is carried out an analysis of operation engineering-economic properties, values of driving dynamics, strength, fatigue life and a life cost of three car versions under consideration. The comparison of designs according to all parameters mentioned allowed defining the fact that taking into account the specificity of the domestic legislation, requirements of standard-regulation documentation for rolling-stock designing, and also the interests of transport operators the most efficient design scheme is a platform-car with a stationary lower level of a load platform on a base length and a bearing design of a truss type.
