Cityjet eco in landscape

ÖBB Cityjet eco

1st approved battery train in Europe celebrates its premiere in passenger service.

The railcar developed by Siemens Mobility and ÖBB is the CO2-neutral solution for use on non-electrified routes. There is a battery system on the roof of the train that charges itself with the green traction current via the pantograph on electrified sections. Compared to diesel vehicles, the ÖBB Cityjet eco can then cover the non-electrified sections of the route in Lower Austria, Upper Austria and Styria with almost no noise or emissions. From 2 September 2019, this prototype train with an electro-hybrid battery drive will be in real passenger operation in Lower Austria to gain further knowledge.

Tailored innovation

An existing ÖBB Cityjet Desiro ML was converted and equipped with the new system with little effort so that the train can move seamlessly from an electrified to a non-electrified route. This innovation is tailor-made for the Austrian rail network: Almost a quarter of the railways in Austria are not yet electrified - around 1,300 km.

This lighthouse project has the potential to further massively reduce the greenhouse gas emissions that still exist in Austrian rail traffic and at the same time to raise the offer for passengers to the comfortable Cityjet level: WITHOUT having to change trains!


The construction of the interior, together with the attractive design, gives the train a generous feeling of space with comfort and safety. This is ensured, among other things, by appealing color schemes, comfort seats and folding tables.
