First battery rail car on the Royal Bavarian State Railways (1887)

In 1887, the Royal Bavarian State Railways introduced the first German accumulator railcars. These battery-powered vehicles offered advantages such as avoiding fossil fuels and eliminating the need for expensive continuous electrification infrastructure like overhead catenary.

Background and detail

Background. The Royal Bavarian State Railways was the state railway company for the Kingdom of Bavaria. By the end of the First World War, it had grown into the second largest German state railway. From 1886 to 1906, the organisation came under the Head Office of the Royal Bavarian State Railways (Generaldirektion der königlich bayerischen Staatseisenbahnen), the administrative body under which the 1887 battery railcar introduction occurred.

Technology. Battery electric multiple units, or accumulator railcars, are powered by rechargeable batteries driving traction motors. Their primary advantages include the elimination of fossil fuel use, no exhaust emissions, and the avoidance of costly continuous infrastructure such as electric third rail or overhead catenary. This technology allowed for economic viability on certain lines without full electrification.
