Railway infrastructure manager

A railway infrastructure manager is "any body or undertaking that is responsible in particular for establishing and maintaining railway infrastructure. This may also include the management of infrastructure control and safety systems. The functions of the infrastructure manager on a network or part of a network may be allocated to different bodies or undertakings"[1][2] This includes mainly railway track and catenary, if the railway line is electrified, and respective command and control systems. It can also include the stations and power supply network. A significant proportion of these companies are state-owned monopolies, responsible for all or most of the railway infrastructure within a given country. In the European Union (EU), separation of infrastructure and operation is mandated by law, so train operation is performed by another type of company, a railway undertaking which must be provided with non-discriminatory access to any railway path within the EU.[3] Outside the European Union it is possible that the same company is owning the infrastructure and also operating trains and in that case this designation might not make sense. Infrastructure managers charge for the use of its network.
