Greener Driving System

Be on time, Save energy

This system monitors and analyzes conventional train operations, and generates Energy Saving Guidance for improvement energy consumption.

Operation and Control


Energy saving running profile

According to train dynamic conditions, route profiles, time tables, and train diagrams, Basic Energy Saving Running Profile is calculated by the Planning System, and the on-board system adjusts the profile based on real-time conditions.

Smooth Assistance by Graphical Human-Machine Interface (HMI)

A simple HMI with sound assistance has been created based on drivers’ recommendations. This HMI is also capable of displaying their energy consumption.

Energy meter interface

Records energy consumption and transfers data to the ground-based system

Benefits & Value

Save Energy : Recorded 10% Reduction on average in energy consumption*

This system monitors and analyzes conventional train operations, and generates Energy Saving Guidance for improved energy consumption in order to ensure an energy-conscious cycle.
* in Field Operation Test. Please see below for the details.

Keep schedule

Energy Saving Guidance is based on Timetable. If the train is delayed , this system calculates a new eco-running profile to recover and be on time.

Improve driving skills

Drivers will develop smart driving skills through the energy-conscious cycle. In this system, driving results and scores will be displayed to the driver, enabling them to improve their motivation.
