CAF has premiered its Civity battery-electric multiple unit (BEMU) at InnoTrans 2026, giving the trade fair's visitors a first public look at the Spanish manufacturer's battery-equipped regional train.

The debut places CAF among the manufacturers using Berlin's biennial show as the launch stage for battery traction, a technology now central to regional operators' plans to decarbonise non-electrified lines without the cost of overhead wiring.

What is on show in Berlin?

The Civity BEMU on display at InnoTrans 2026 is the battery-electric variant of CAF's Civity regional platform. The manufacturer presented the unit in the exhibition halls as a premiere, marking the first time the public and industry customers have been able to inspect the vehicle directly.

For regional operators, the significance is operational rather than cosmetic. Battery-electric multiple units are designed to run on non-electrified corridors using on-board energy storage, recharging where the wire exists, at stations, or via charging infrastructure. That removes diesel traction from branch and regional lines while avoiding the capital cost of full electrification — the cost outcome that makes the class attractive to operators weighing fleet renewal against network investment.

Why does the timing matter?

InnoTrans remains the industry's largest trade fair, and manufacturers consistently time first public presentations to coincide with it to reach the maximum concentration of operator procurement teams, leasing companies and regulators in one place. CAF's decision to premiere the Civity BEMU at the 2026 edition signals the company wants the vehicle in front of buyers as regional fleets across Europe come up for renewal and as operators face tightening emissions requirements on non-electrified routes.

The presentation is a claim by the supplier, and buyers will measure it against their own fleet plans: range under battery power, charging arrangements, capacity, and lifecycle cost are the figures that will decide whether the Civity BEMU wins orders. As with any show premiere, the static display marks the start of that commercial scrutiny rather than the end of it.

What comes next?

The InnoTrans 2026 premiere positions the Civity BEMU for the order competition on European regional networks, where battery traction is steadily replacing diesel as the default choice for lines without overhead contact wire.
