Yes, Prussian. Battery Railcars are in-fact old enough to have been used by an organisation formed by the State of Prussia, and use them that did! First ordered in 1909 they were a common sight on secondary and rural lines throughout the German Empire, then the Weinmar Republic, then Nazi Germany and then East and West Germany, working reliably until 1964. How did they avoid the issues of battery degradation that Lithium Ion batteries have? Honestly I'm pretty sure they used lead acid batteries instead. Ultimately 163 of those quiet machines would be built and then eventually replaced by ETA-150's, a far more modern design… of battery railcars.
