- Infrastructure manager — state-owned manager of the national railway infrastructure and the body responsible for executing infrastructure development works; registered at Karolou 1-3, 104 37 Athens. The 2026 Network Statement is published in the name of the Hellenic Railways Single-Member Société Anonyme (HR S-M S.A.) and the company's own contact directory is headed 'ΣΕ ΜΑΕ / Σιδηρόδρομοι Ελλάδος' with @hellenicrailways.gr mailboxes, but the buyer string on TED is not uniform: notice 577354-2026 of 20 August 2026 prints ΣΙΔΗΡΟΔΡΟΜΟΙ ΕΛΛΑΔΟΣ ΜΑΕ while notice 144923-2026 of 2 March 2026 still prints ΟΣΕ Α.Ε., and other 2026 procedures carry ΟΡΓΑΝΙΣΜΟΣ ΣΙΔΗΡΟΔΡΟΜΩΝ ΕΛΛΑΔΟΣ Α.Ε., so some procedures carry the new name and others still print the old one; the website remains ose.gr and hellenicrailways.gr redirects to it
