EVALUATION OF THE EFFICIENCY OF DIESEL LOCOMOTIVES ON THE SECTION OF MAROKAND - KATTAKURGAN OF UZBEK RAILWAY

A comparative analysis of the efficiency of using diesel traction locomotives in the Marokand - Kattakurgan section of the Uzbek Railway for freight trains with and without stops at intermediate stations, siding and separate points is given. Mathematical models of conducting freight trains by diesel-powered locomotives were developed, specific resultant forces of the train were calculated and built in the modes of traction, idling and braking, curves of the speed of movement and time of the train on the considered real railway section. The kinematic parameters of the movement of freight trains and the main energy indicators of the transportation work of diesel traction locomotives on the Marokand - Kattakurgan section of the Uzbek Railway in quantitative and monetary terms are substantiated, and regression equations for their determination are obtained. The advantage of three-section trunk (train) freight diesel locomotives UzTE16M3 over similar diesel locomotives of the 3TE10M series has been proved. The results of the study are recommended to drivers - instructors and specialists of the locomotive complex operation workshop, whose professional activity is directly related to the implementation of freight traffic and the transportation of diesel traction locomotives on the real section Marokand - Kattakurgan of JSC Uzbekistan тemir уollar
