Freight locomotives of Ukrainian railways has worked regulatory deadline, more than 300 sections ofМ62, 2М62, 2М62У were built in 1975-1987. An excess lifespan led to decrease economic indicators due toincrease fuel consumption, increase the volurrie of repairs, environmental degradation. Neverthelessfinancial and economic situation does not allow renewing the locomotive fleet. That is why modernization oflocomotives is carried out. We have the experience of complex modernization of diesel locomotives type M62by design of general motors and general electric firms. Its cost value is equal to 80-85% of new diesellocomotive cost. The replacement of outdated engines is less radical, it showed high efficiency.
