The organisational mechanism of emission reduction at modernisation of diesel locomotives is proposed, including corresponding procedures of rationing, ranking and stimulation, which is based on the ranking estimations of emission indicators formed taking into account national and regional requirements to diesel locomotives. The environmental friendliness ranks of the modernised diesel locomotive are defined: satisfactory – if its emission indicators meet the national standards, good – if these indicators meet the national or regional standards of the countries of advanced diesel locomotive building, and excellent – if these indicators meet the best world environmental standards. Calculations of environmental friendliness ranks of domestic and foreign diesel locomotives modernised with the help of this kind of research and development are given. The results obtained were used in developing a concept of the system of environmental requirements for locomotives of ‘Russian Railways’ JSC.
