[2] In order to comply with EU regulations on opening up railways to competition, SNCF was to be split into two parts; SNCF would continue to own trains whilst RFF managed infrastructure.
However, many infrastructure staff were never transferred to Réseau Ferré de France, so RFF delegates work to SNCF Infra.
[3] In October 2012, Frédéric Cuvillier, the French Minister for Transport, announced plans to combine rail infrastructure into a single organisation, Gestionnaire d’Infrastructure Unifié, or GIU.
[4] SNCF Infra has a number of subsidiaries, including SYSTRA,[5] and the Direction de la Circulation Ferroviaire (DCF), a nominally independent body which manages traffic on behalf of RFF.
On 1 January 2015, Réseau ferré de France (RFF) merged with SNCF Infra and the Direction de la circulation ferroviaire (DCF) and became SNCF Réseau.
