In January 2011 the Greek government proposed a reorganization of the system, which involves reduction of the separate companies to just two, one for tram and metro and one for conventional and trolley buses. In March 2011, the Greek Government passed Law 3920 to allow Attiko Metro Operational Company to absorb Athens-Piraeus Electric Railways S.A. and TRAM S.A. and create a new company "STASY S.A.". Also ETHEL S.A. and ILPAP S.A. were merged in "OSY S.A.". The mergers were officially announced on June 10, 2011. While mergers at the top management level took place quickly, integration of the former companies at operations and support level proceeds slowly.
As of July 2011, the Athens Mass Transit System consists of:
OSY and STASY is wholly owned by OASA. TrainOSE is coordinated by Athens Urban Transport Organisation, a state-owned company.
ISAP, ETHEL and ILPAP were wholly owned by OASA S.A.. AMEL and Tram S.A. until June 2011 were subsidiaries of Attiko Metro S.A., a company that is currently wholly owned by the Greek government.
TrainOSE S.A., which absorbed the former Proastiakos S.A. in 2007, became independent of the OSE group in 2008 and is now a separate private company.
OASA regularly conducts street photography and videography competitions both in black-and-white and in colour for photos taken while inside its means of transport.
