Development of an energy efficient train traffic control system for saving electricity

In order to decrease railroad train energy consumption, an energy efficient railroad train traffic control system is in development. The control system reduces the running energy consumed by assigning a number of seconds of scheduled margin times to platforms at inter-stations. The system is most useful for urban trains. While attending to train delay, the control system tweaks the arrival and departure times at railroad stations, without passengers being aware that anything is different.

Punctual train operation with energy-saving Driving Advisory System in dense traffic railway

This paper describes a concept based on energy-efficient train operation technology. It is known that the energy-saving train driving operation for a train takes the form of an operation of power-coast-brake. However, drivers cannot operate in such strategy when the previous train delays. Some drivers experientially drive trains without stopping between stations. But it is very difficult for less-experiential drivers to drive without stopping stations. We have developed prototype hardware and software for helping drivers operation and evaluated energy consumption and running time by numerical simulation.
