Environmentally-Friendly, Energy-Saving Trains, Part Two

Kawasaki Heavy Industries is developing a high-speed train named the environmentally friendly super express train (efSET), that can reach speeds of 217 mph (350 kph). This train design is more energy-efficient and less noisy and uses 19% less energy than other trains currently on the Japan National Railway (JNR) rails. It's lightweight, aerodynamic, and uses "regenerative braking technology" to capture energy lost during braking. Japan currently has the world's fastest train network, with trains reaching up to 180 mph (300 kph).
