Siemens Mobility and the Danish operator Midtjyske Jernbaner (MJBA), celebrated a historic milestone for Denmark’s green transition. On 19 December 2025, H.M. King Frederik officially inaugurated the country's first battery-powered trains. Seven Mireo Plus B trains entered passenger service on the Holstebro - Skjern and Vemb - Lemvig - Thyborøn lines, replacing the old diesel fleet and providing quiet, emission-free rail transport in the West Jutland region.
The deployment of these battery-powered trains marks a significant step in Denmark's efforts to decarbonize its public transport system. For Midtjyske Jernbaner, it fulfills the ambitious goal of becoming Denmark's greenest railway. The new trains offer commuters and families in West Jutland a significantly improved travel experience with modern amenities, higher frequency, and increased capacity.
"Six years ago, when we decided to replace our diesel trains with more climate-friendly alternatives, we knew very little about the technology. Today, we are proud to launch Denmark’s first battery-powered train. It has been a long and exciting journey, and we would like to extend our heartfelt thanks to Siemens Mobility for the excellent collaboration,” says Martha Vrist, CEO of Midtjyske Jernbaner.
The Mireo Plus B two-car units offer seating for 127 passengers, a top speed of 140 km/h, and a battery-powered range of about 80 km. It features a battery-hybrid drive and can be charged via the 25 kV overhead line in electrified sections.
The fleet for MJBA will offer passengers a significantly improved travel experience with modern amenities such as Wi-Fi and passenger information systems, increased comfort, and higher capacity. The order, placed in 2022, was the first for Mireo Plus B trains outside of Germany, where the Mireo platform is already a success with over 295 trains in operation.
