The history of Spanish Railways dates back to 1837, in Cuba, Spanish territory at the time, at the line La Habana- Bejual.

In 1848, the first line in Spain started operating between Barcelona and Mataró.

For almost one century, many private companies built and operated their own lines, until RENFE, the National Railways Company, was created in 1941.

Following European Union regulations, and in order to accomplish railways liberalization, RENFE split in 2005 into Adif (the Infrastructure Manager) and RENFE Operadora (railway undertaking in charge of transport operation, both passengers and freight).

In 2005, rail freight transport was fully liberalized in Spain. Currently, more than 20 companies are licensed to operate. Passenger transport is due to open shortly to competition on the East Corridor (Madrid- Levante), for both High Speed and conventional traffic.

In 2014, Adif split into Adif (conventional railways) and Adif High Speed (management and construction of new HS lines). Both companies remain fully coordinated for operational matters.

In September 2015, Spain passed the new Railway Sector Act, in order to implement new EU regulations.



Adif and Adif High Speed keep working to improve our business and operational performance, ensuring the highest levels of safety and quality of service for our clients, both in Spain and abroad. Adif International, as part of that strategy, will continue sharing with our international partners all managerial and operational improvements developed and implemented in our national market.

Concerning the conventional network, Adif will continue working on the enhancement of existing lines, in order to ensure safer, punctual, reliable and cost-efficient railways, and focusing particularly on Commuter lines.
