Administrador de Infraestructuras Ferroviarias

Madrid, Spain

ADIF, which stands for Administrator of Railway Infrastructure in Spain, is an organization responsible for managing and maintaining the extensive railway infrastructure network in Spain. Its establishment aimed to modernize and improve the country’s railway system, contributing significantly to the efficiency and safety of rail transportation in Spain. 

Historical Background: 

ADIF’s origins are rooted in a notable restructuring of Renfe, Spain’s railway entity. On January 1, 2005, Renfe underwent a transformation that resulted in the division of its operations. ADIF emerged as the entity responsible for preserving and managing the country’s railway infrastructure. In parallel, Renfe Operadora was established to focus on passenger and freight transportation. This pivotal transition marked a milestone in Spain’s railway history, introducing a more organized and segmented railway system under a public enterprise framework.  


At its core, ADIF is dedicated to creating a secure, sustainable, and efficient railway system that facilitates the movement of passengers and freight across Spain. The organization is guided by several key objectives, including the continuous improvement of railway infrastructure, the promotion of innovative technologies, and the optimization of operations to meet the evolving demands of modern transportation.

These collaborations foster innovation, knowledge exchange, and the implementation of best practices in the railway industry, further enhancing the quality of rail services in Spain.
