On 6 April Attiko Metro published a call for tenders for the first section of a new metro line in Athens, Line 4, which will be the first automated line in Greece. Section A, running from Alsos Veikou to Goudi, will be approximately 13km long and will have 14 new stations.
The scope of the contract will include among other final design and construction of the line, stations and a new operations control centre, as well as the supply of trains and training of operations and maintenance staff.
Line 4 will complement the city’s existing three lines (line 1 – former ISAP and lines 2 and 3 of Attiko Metro). Its U-shape will include two radial branches (towards Galatsi and towards Maroussi) and one central part connecting the branches with busy and densely populated areas such as Kypseli, Exarchia, Kolonaki, Kaissariani, Ilissia, Zografou and Goudi. It will be connected with Line 2 at Panepistimio Station and with Line 3 at the existing Evangelismos Station.
Signalling and the train control system will be based on CBTC technology. Central control of the trains and stations will be done exlusively from the new OCC, which will also be designed to take over the control of the existing metro lines and tram lines. It will be located in a new building to be constructed in an area within Sepolia Depot.
Stations wil be 110m long and equipped with platform screen doors.
Construction will include a 10km double-track tunnel, as well as a connecting single-track tunnel (approximately 840m long) including start-end turnouts, which will connect Line 4 with the existing connecting tunnel of lines 2 and 3.
