Infrastructure Manager (EU definition)

An infrastructure manager is any body or firm responsible for the operation, maintenance and renewal of railway infrastructure on a network, and for participating in its development, as defined in Article 3 of Directive 2012/34/EU. The role covers track, signalling, stations and traffic management — the fixed side of the railway, as distinct from running trains.

EU law treats the infrastructure manager as a role that must be kept apart from train operations. The reason is structural: a rail network is a natural monopoly, and whoever controls the track decides who runs, when, and at what price.

Two tasks are classed as essential functions: train path allocation and infrastructure charging. Decisions on both must be taken independently of any railway undertaking, so that an incumbent operator cannot use control of the network to disadvantage its competitors.

Separation models

Member States implement the separation in different ways. Some place the infrastructure manager in a fully independent state company — in the Netherlands, ProRail manages the network outside the incumbent operator’s group — while others keep it as a ring-fenced subsidiary inside a holding structure alongside the group’s train operators.

Both models are permitted, but holding structures carry additional safeguards on financial transparency, impartial traffic management and the independence of the essential functions. These safeguards were tightened by the governance pillar of the 4th Railway Package through Directive (EU) 2016/2370.

The infrastructure manager’s obligations toward the market are set out in its network statement: the annual document that describes the network, the conditions of access and the charging rules. Every railway undertaking seeking capacity deals with the infrastructure manager on those published, non-discriminatory terms.
