Анализ эксплуатационных параметров грузовых тепловозов на железных дорогах Литвы

Freight trains optimal movement parameters are analysed in this paper. When transporting goods with freight trains, there are exhausted all the possibilities of that train for saving fuel and oil, but that depends on a lot of exploitation and ambient factors. Depending on trains (freight) weight and rail track profile, changes the resistance affreight train movement, that’s why looking through this point of view, in counting rail track profile (curves and slopes), optimal velocity of the freight train are analysed, which it can support during its travel and the optimal (largest) freight it can transport. Finally, basic conclusions are given
