The DDFlyTrain research project, conducted by Ricardo, Artemis Intelligent Power (a group company of Mitsubishi Heavy) and Bombardier Transportation, (earlier post) has projects a fuel savings of around 10% based on the use of high speed flywheel brake recovery technology retrofitted to Diesel Multiple Unit (DMU) rolling stock. This order of saving means that the technology has a potential return on investment (ROI) of inside five years.
