FLIRT Akku 2-car unit for Pfalznetz
The FLIRT Akku is the battery-operated version of the FLIRT series. In late 2021, the association ZÖPNV Süd commissioned Deutsche Bahn with the acquisition of 44 two car FLIRT Akku units. The battery-operated trains will cover the routes of the Palatinate network starting in December 2025.

Designed for non-electrified and partially electrified sections, the FLIRT Akku is particularly versatile. The batteries can be charged both while the train is travelling with a connection to an overhead contact line, as well as at electrified terminal stations. The braking energy is also fed back into the batteries. This allows the train to be used in a manner that is both efficient and saves energy. The train, which is equipped with lithium-ion batteries, will operate on the Palatinate network and consist of two cars with extra-long car bodies. The fully air-conditioned Deutsche Bahn FLIRT Akku offers bright passenger compartments with a passenger WLAN system, as well as generously proportioned multipurpose areas. There is space for a total of 325 passengers, including 172 seated passengers.
