ISAP

I.S.A.P. is the acronym for the Athens-Piraeus Electric Railways (Greek: Η.Σ.Α.Π. - Ηλεκτρικοί Σιδηρόδρομοι Αθηνών-Πειραιώς, Ilektrikoi Sidirodromoi Athinon - Pireos), the oldest urban rapid transit system of Athens metropolitan area in Greece. Opened as a suburban railway line connecting Athens with the nearby major port city of Piraeus, it was gradually converted to full rapid transit operations, making it one of the oldest metro lines in the world. The current line evolved from the older Athens & Piraeus Railway and Lavrion Square-Strofyli railway. In June 2011 ISAP was absorbed by a new transport company, STASY S.A.
