Network access
To access the General Interest Railway Network (RFIG), railway undertakings must hold the corresponding license and safety certificate, which are issued by the AESF (Spanish Railway Safety Agency).
The AESF is the authority responsible for railway safety, as established in Law 38/2015 of 19 September, on the Railway Sector, which carries out the management, inspection and supervision of the safety of all elements of the railway system: infrastructure, rolling stock, railway personnel and railway operation.
