Motivation

There are still significant proportions of non-electrified railway lines in the rail network in the Federal Republic of Germany. These have to be operated using diesel trains. Power-split electrical and mechanical hybrid drives offer great potential in the future to enable pollutant-free train operation in the station area and on tunnel sections and to significantly reduce the fuel consumption of multiple-unit diesel trains.

Research objectives

The objective of this project is the development of a hybrid drive concept for commuter trains, which can be switched between an emission-free, pure electric mode and a diesel-powered electric-power-split mode.

  • Identification of an optimal transmission structure for a multiple-unit commuter train
  • Development of a suitable operating strategy
  • Development of an electrical storage concept
  • Assembly and testing of a demonstrator to validate the drive concept
