CHOICE OF OPTIONS OF LOCOMOTIVE CHARACTERISTICS TAKING INTO ACCOUNT OPTIMUM EFFICIENCY

The saturation of the locomotive park railways with various series locomotives does not always correspond to their effective use given inherent special characteristics. Modern conditions require all participants in design, construction, operation and repair make correct well-founded decisions. variety locomotives, which provide different requirements economic activity, is basis operation. This especially applies that are purchased abroad. As experience has shown, they adapted real our country. is, first all, intensive exploitation lack adaptability base maintenance rolling stock. On other hand, capacity range, for example, freight were purchased, traditional ones, take into account both length warehouse receiving-departing routes, etc. In country, sufficient been accumulated there appropriate a comprehensive coverage tasks design construction provision industrial enterprises transportation, as well population intercity suburban transportation. Unfortunately, many factors currently even minimal needs updating fleet modernization operational activities railway impossible. these conditions, perhaps most important task correct, justified choice characteristics, taking its technical condition. article deals procedure forming characteristics based on efficiency criterion. Based verification corresponding substitutions dimensionless scales pure indicators an set some solutions determined, optimal solution formed selection specific use. data shown decision-making procedures regarding locomotives.
