Line 2 (Thessaloniki Metro)

Line 2 of the Thessaloniki Metro, also known as the Kalamaria Extension (Greek: Επέκταση Καλαμαριάς), is a deep-level underground rapid transit line in Thessaloniki, Greece, connecting N. Sid. Stathmos in the west with Mikra in the south-east. The section of the line between Neos Sidirodromikos Stathmos and 25 Martiou stations is set to open in 2020, with the rest of the line becoming operational in 2021.[1] Venizelou and Aghia Sofia stations will become operational in 2023 and 2021, respectively.[1] Of the line's 16 stations, 11 are also stops for Thessaloniki Metro's Line 1, as they will share tunnels.[2]

Construction costs for the line (between Nomarhia and Mikra) are set at €518 million ($584 million).[3]

Line 2 is to be extended further, with an eastern extension towards Macedonia International Airport (4 stations) and a loop extension in the west (9 stations).[4] A priority for Attiko Metro, the company overseeing construction, is the western extension. This is so as to provide access to the metro to working class suburbs, since the airport will be serviced by a 10-minute shuttle bus to Mikra, the eastern terminus of Line 2.[2] Originally the two extensions were to be separate lines, but they were merged into a single circular line in 2018.[5]
