# Elliniko Metro

Elliniko Metro (Greek: Ελληνικό Μετρό), formerly Attiko Metro (Αττικό Μετρό) until May 2023, is a Greek State-owned company who is responsible for the development and construction of the Athens Metro and the Thessaloniki Metro, as well as the Athens Tram.
Headquartered in the Ellinoroson neighbourhood of the center of Athens, the Greek government created the company in July 1991: Elliniko Metro's original purpose was to oversee the delivery of the Base Project of the Athens Metro, which opened in three stages, in 2000 and 2003. Elliniko Metro also owned and operated the Athens Metro and Tram until June 2011, when STASY took over that role.

## History

The Greek government established Elliniko Metro as Attiko Metro (Greek: Αττικό Μετρό) on 18 July 1991, under Law 1955/1991. The original purpose of Attiko Metro was to oversee the delivery of the Base Project of the Athens Metro, whose contract had been awarded to the Olympic Metro consortium of 23 companies in the previous month. The Base Project consisted of two lines with a total length of 17.6 kilometres (10.9 miles) and 20 stations, and opened in three phases from 28 January 2000 to 22 April 2003.$^{:3}$ The Greek government then assigned Attiko Metro the role of developing and build the Thessaloniki Metro in December 2003, and any future extensions to the Athens Tram in 2013.
On 18 May 2023, Greek Prime Minister Kyriakos Mitsotakis announced that in advance of the opening of the Thessaloniki Metro in 2024, Attiko Metro would change its name to Elliniko Metro.

## Organisation

The Greek government is currently the only shareholder of Elliniko Metro. Law 1955/1991 allows the partial privatisation of Elliniko Metro in the future, but the Greek government must retain a controlling interest of at least 51% over any resultant company: Elliniko Metro may also only merge with mass transit organizations that operate within the area of the former Attica Prefecture.

## Current operations

Elliniko Metro is currently responsible for the development and construction of the Athens Metro, the Thessaloniki Metro, and the Athens Tram.

## Former operations

Elliniko Metro previously had two operational subsidiaries to operate and maintain Metro lines 2 and 3, and the current Athenian tram network: on 17 June 2011, AMEL and Tram S.A. merged with Athens–Piraeus Electric Railways (ISAP) to form STASY, a subsidiary of Transport for Athens (OASA) instead of Elliniko Metro:
* The Attiko Metro Operation Company (Greek: Αττικό Μετρό Εταιρεία Λειτουργίας, Attiko Metro Etaireia Leitourgias), commonly abbreviated to AMEL, operated and maintained the infrastructure of Lines 2 and 3 of the Athens Metro, except for the surface section of Line 3 between Doukissis Plakentias and Athens Airport. Headquartered at the Sepolia Metro Depot at 94 Kifissou Avenue, AMEL was established on 15 February 2001, three years after Law 2669/1998 allowed Elliniko Metro to operate and maintain Lines 2 and 3.
* Tram S.A. (Greek: ΤΡΑΜ Α.Ε.) operated and maintained the infrastructure of the Athens Tram, which by June 2011 consisted of 35 Sirio trams and 48 stops.$^{:47}$ Headquartered at the tram depot in Elliniko, Tram S.A. was established in March 2001.
The logos of both companies were the same as the system that they operated.
