In 1959, Uzinele 23 August(former Nicolae Malaxa S.A.R.) built two DMUs named "Sageata Albastra" (Blue Arrow) to operate trains between Wien and Constanta, on the Black Sea shore. Finally, those trainsets never leaved Romania. The power cars are (A1A)' 2' type. Originally, the diesel engines were of 730 hp, and the maximum speed was 110 km/h. Here we see a Sageata Albastra/Blue Arrow train at Constanta in the Summer of 1966 prior to leave the station as Constanta-Bucuresti Nord fast train.
