New high-speed trains need modern energy management methods to reduce energy consumption. A fuzzy method based control method was used to solve this problem in this paper and evaluated the results on basis of data in Tehran metro line 3. Recovering the maximum amount of train kinetic energy when it is in the braking mode and optimal division of traction systems demand between energy storage sys...
Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
Cross-line trains, as a link between high-speed and conventional rail networks, will increase the complexity of transport organization and lead to significant challenges in dispatch coordination between the two systems. Based on the characteristics of high-speed transport organization, this paper deals with the necessity of dispatch coordination between high-speed and conventional lines from th...
