Important information for vehicle owners

The vehicle owner is responsible for ensuring that a valid traction vehicle-side ETCS key is present on the vehicle. Any vehicle-side KMC is necessary for the creation of this ETCS key on the traction unit.
ÖBB-Infrastruktur AG offers an on-board KMC that creates on-board ETCS keys – see Home-KMC as a Service (HaaS).
