DRS6-4-1500, c/n 73216 to 73219, were delivered new to Chemins de fer Tunisiens as CFT 040 DA 1 to 4 in 1946.
They were later renumbered as CFT 040 DA 301 to 304, when 040 DA 1 to 33 were delivered by Alsthom in 1950/52.
According to some sources, they were also renumbered as 040 DA 34 to 37, but I never found any evidence of this.
CFT 040 DA 301 to 304 were sold to Chemins de Fer du Maroc in 1958, see Morocco
