RENFE (Spanish National Railways Network) was created in 1941, with the unification of the existing railway companies in Spain into a single state-owned company. In 1975, RENFE began a period of comprehensive reforms for the purpose of turning the Spanish railway network into an efficient alternative for transporting goods and passengers. As a result, Cercanías commuter services were introduced to cities such as Madrid, Barcelona and Malaga. In 1992 RENFE opened the Madrid-Seville high-speed line, coinciding with the opening of Expo'92. On 1 January 2005, RENFE’s legal monopoly came to an end and two successor companies were established; Renfe, responsible for transport of freight and passengers and Adif (Administrador de Infraestructuras Ferroviarias) responsible for managing lines, stations and communications. RENFE was divided into Renfe-Operadora (operations) and ADIF (infrastructure) on 1 January 2005.
