Development of Energy-saving Driving Methodss 

Because approximately 70% of the energy consumed in JR East is used for train operation (driving energy), we are developing energy-saving driving methods in order to reduce the driving energy consumption.

We developed a method to create the driving patterns with less energy consumption (energy-saving driving patterns) by dividing the driving patterns of various trains in operation into sections and optimizing them in relation to factors such as time and speed. We achieved the energy reduction of up to 20% through test operations on the Chuo line.
