Hellenic Railways Organisation
In Greece eight diesel DMU-2 Desiro trains (OSE class 660) were temporarily in service with the Hellenic Railways Organisation (OSE) during 2004–2006, and again in 2007 on the Athens–Chalkida line and on the Athens suburban railway lines (Proastiakos). Afterwards they were returned to their owner (Hellenic Shipyards S.A.) in December 2007. In the late 2008 Hellenic Shipyards/MAN-FERROSTAAL leased the eight units to Hungary with a contract for 20 years.
