The article considers issues of researchers’ work assessment of sectoral research institutes in the Russian Federation. The authors investigate the advantages and disadvantages of the existing system of scientometric indicators with relation to the researchers’ publication activity increase. Practical solutions are proposed to harmonize the internal and external motivation of the researchers’ work of the sectoral research institute in order to ensure the effectiveness of their scientific activities, the implementation of key indicators of the effectiveness of scientific work and to promote the economic and innovative effect of the institute activities. The authors proposed a conceptual system for stimulating the work of researchers through authorship in scientific publications and evaluated its effectiveness. The scientific novelty lies in the development of a system of incentives for authorship in scientific publications to employees of the Railway Research Institute. The practical significance of the study lies in the possibility of applying the incentive system in many sectors of the modern economy.

Introduction. The tasks of increasing energy saving in heating systems for passenger cars of diesel trains are currently relevant. As an alternative source of energy for these systems, the possibility of using the waste heat of the diesel locomotive engine is analysed.Materials and methods. The article provides an analysis of the engine waste heat sources, cooling water and exhaust gases. A schematic diagram of exhaust gas heat exchanger for its use in the heating system of passenger cars has been deve loped. As a possible heat-exchange surface of the waste heat exchanger, plate-ribbed, coiled and tube surfaces with longitudinal boundary layer turbulators are proposed. The required area of this surface for the maximum power of the heating system for a passenger train is determined.Results. The article shows the possibility of using engine exhaust heat in the heating system of a 15-car passenger train without involving third-party energy sources.Discussion and conclusion. The obtained results demonstrate a sufficient potential for increasing the efficiency of using the diesel engine fuel energy when utilising its waste heat for the heating system of passenger cars. The selection of a waste heat exchanger is justified based on a performance of 50 % of the peak load on the heating system at the middle position of the controller.
