GAIAOSE


GAIAOSE S.A. is a Greek state-owned property management company that owns and operates real estate of the Greek railway network, such as stations. From 2014 to 2025, it also managed and leased rolling stock to train operating companies, such as Hellenic Train.

History

GAIAOSE was created on 3 October 2001, as a railway real estate subsidiary of the Hellenic Railways Organisation. According to Kathimerini in June 2002, GAIAOSE was the second largest landowner, with a total property value of €2 billion. In December 2014, GAIAOSE became the administrator for the railway rolling stock, at the behest of the Greek State. In 2023, 123 older, disused and condemned rolling stock units were set for auction in the first pilot scrapping project, as part of the fleet management program
of the Ministry of Infrastructure and Transport.
In October 2025, Greek Railways took over the management of rolling stock from GAIAOSE, leaving GAIAOSE in charge of developing and managing railway real estate, including stations. The transfer of rolling stock from GAIAOSE occurred as part of the restructuring of the Greek railway network in the aftermath of the Tempi train crash in 2023.
