Headquarters: Spain — Public rail-infrastructure management

ADIF

Also known as: A, d, m, i, n, s, t, r, o, e, f, u, c, v

Spanish public rail-infrastructure manager.

ADIF manages Spanish railway infrastructure. In 2026 the European Public Prosecutor’s Office opened two investigations into possible EU-fund fraud on the Madrid–Seville line and investigators sought documents from ADIF. Police also requested contract files in the Koldo case. None of this proves corporate wrongdoing by ADIF.
