Railway Undertaking (EU definition)
A railway undertaking is any public or private undertaking licensed under Directive 2012/34/EU whose principal business is to transport goods or passengers by rail, with the requirement that it ensures traction. The definition includes companies that provide traction only.
The railway undertaking is the operating counterpart to the infrastructure manager: it runs the trains, while the infrastructure manager provides the network. The two roles are legally distinct even where they sit inside the same corporate group.
The definition is deliberately ownership-neutral. A state incumbent and a private entrant hold the same legal status on the network — DB Cargo and a single-locomotive traction provider are both railway undertakings, with the same access rights and the same obligations.
What the status requires
To operate, a railway undertaking needs a licence, a single safety certificate covering its area of operation, adequate insurance and an access contract with each infrastructure manager whose network it uses. The licence is issued by a national licensing authority and is valid throughout the EU.
The status carries access rights that have expanded in stages: rail freight has been open to competition across the EU since 2007, international passenger services since January 2010, and domestic passenger services under open access since the December 2020 timetable change following the 4th Railway Package.
Without the railway undertaking as a defined legal category, market opening would have no subject: the access rights, licensing rules and safety obligations of EU rail law all attach to this status, not to nationality or ownership.
