[1] The CO created the "Compagnie franco-hellenique des chemins de fer" (CFFH) as a subsidiary company.

[3] Overall, this line was 165km[4] long route from the Aegean Sea port city Alexandroupoli to Ormenio, the last station in Greece before entering Bulgaria.

[6] These rights survived until 1971 when TCDD inaugurated its own line from Pehlivanköy to Edirne & Svilengrad fully on Turkish territory.

The former CO station in Edirne Karaagaç, west of the Maritsa, was not no longer served, nor by TCDD nor by SEK and went into disuse.

During the Greek Civil War until 1949, the trains operated only by daylight and were supplemented with empty freight cars in front of the locomotive and armed with escort to protect them from mines.

SEK took over operations of the line and rolling stock, effective 1 January 1955, and the CFFH ceased to exist.
