This DVD traces the history of the battery powered railcars that were used on rural branch lines around Germany throughout the 20th century. Features several different types of railcar and examines the development of battery power, as well as looking at how the units were used, up until the withdrawal of the final vehicles in the 1990s. Much of the footage is archive in nature, but the DVD also includes more recent material looking at vehicles which are in preservation today. German commentary. 58 minutes running time.
