Influence of speed on energy consumption of freight trains

Investigation of instantaneous and average velocities of train movement, their properties and their application, including calculation of speed coefficients and movement time. Determination of influence of the movement speed and its restrictions, stops and delays onto travel time losses and traction energy consumptions of loaded and empty trains. Time and energy saving estimation due to the application of regenerative braking on the electric locomotive. Development of the recommendations for increasing average speed, decreasing travel time and energy consumption of freight trains.
