Diesel power trains used by the Danish National Railways have been investigated. Energy conservation to be achieved by regenerative braking was calculated for mathematical models of two real railway lines. The hydraulic accumulator used to store energy, was found to be too heavy and voluminous compared to its relatively low energy density. If 100% braking energy can be stored, fuel economy of the system can be 15-25%. Turbo-charged diesel engine, switching the motor off on every idle run, use of an electric or hydraulic retarder to supply heat for the heating system will reduce energy consumption. Regenerative braking would be utilized better in a more flexible time-table than the real one is in case of train traffic. (ERA citation 09:043701)
