According to the updated researches on train energy_economizing control both by domestic and international professionals, this paper designs all computer algorithms. A computer simulation system for train energy_economizing movement has also been developed based on various energy_economizing optimized control methods. By the system, the paper analyzes the energy_saving effects under different target speeds and line geometry. As a result, it shows the energy consumption may be decreased by 14.4% if train target speed increases from 50 km/h to 60 km/h, and suitable track reconstruction may decrease energy consumption by 9.2% and operational costs by 8.9%.
