Attiko Metro

The Athens Metro (, Metró Athínas) is a rapid-transit system in Greece which serves the Athens conurbation and parts of East Attica. It incorporates the former Athens-Piraeus Electric Railways (ISAP), which opened as a conventional steam railway in 1869, and which was electrified in 1904 and is now part of Line 1. Beginning in 1991, Attiko Metro constructed and extended Lines 2 and 3 and the Attiko Metro Operations Company (AMEL) operated these lines from 2000 to 2011. The metro network merged in 2011 when the Greek government created the Urban Rail Transport Company (STASY), a subsidiary of the Athens Urban Transport Organization (OASA).
