context_page_description: I.S.A.P. S.A. or Athens–Piraeus Electric Railways S.A. was a company which operated the Piraeus - Kiffisia line from 1976 to 2011. Piraeus - Kifissia line was the oldest urban rapid transit system of Athens metropolitan area. The line opened in 1869 as a suburban railway line connecting Athens with its port of Piraeus and it was gradually converted to full rapid transit operations, making it one of the oldest metro lines in the world. The line which Isap S.A. operated evolved from the older Athens & Piraeus Railway and Lavrion Square-Strofyli railway.
  In June 2011 ISAP S.A. was absorbed by a new transport company, STASY S.A.
