These locomotives were based at Aghios Ioannis Rentis and Thessaloniki depots and were used mainly for freight trains and for some express passenger trains on Piraeus–Thessaloniki and Thessaloniki–Idomeni mainlines until the early 1970s, when they were withdrawn by the Hellenic Railways Organisation (successor of SEK) due to complete conversion to diesel traction.
