  • Thessaloniki's metro system will expand to Kalamaria on August 27, 2026, integrating a new branch into the existing network.
  • The expansion adds five new stations and approximately 4.5 kilometers to the metro line, with trains running to Mikra or Nea Elvetia.
  • Service frequency will be about three minutes on the common section and 4.5 minutes on the Kalamaria branch, with a total trip from Mikra to the New Railway Station taking 24-26 minutes.

The Thessaloniki metro system is set to expand its reach to Kalamaria with the "25th of March – Mikra" branch officially opening for commercial operation on August 27, 2026. This marks the final institutional step before the new section becomes available to the public.

From Thursday, August 27, 2026, the new branch will operate as a single network with the existing section of the main line.

— Nikos TachiaosThe Deputy Minister of Infrastructure and Transport, Nikos Tachiaos, announced the operational start date and integration of the new metro line.

The expansion adds five new stations: "Nomarchia," "Kalamaria," "Aretsou," "Nea Krini," and "Mikra." This new branch extends the existing metro line by approximately 4.5 kilometers, creating a new route that will operate in conjunction with the main line connecting the New Railway Station to Pylaia.

Trains on the new branch will alternate between heading towards "Mikra" and "Nea Elvetia" at a two-to-one ratio, managed by the same control system. The frequency of service on the common section between the "New Railway Station" and "25th of March" will be about three minutes. On the Kalamaria branch, the average interval between trains will be approximately 4.5 minutes. The entire journey from "Mikra" to the "New Railway Station" is estimated to take between 24 and 26 minutes.

The extension to Kalamaria, with the five new stations, adds approximately 4.5 kilometers to the existing network and creates a new branch after the "25th of March" station.

— Nikos TachiaosThe Deputy Minister described the physical scope and new stations of the metro extension.

This development follows successful completion of inspections and certifications for the infrastructure and systems. Hellenic Metro SA has confirmed the extension's completeness, safety, functionality, and reliability. Additionally, certificates from contractors and an independent certifier, TÜV Rheinland, confirm the completion of all construction, system installations, and performance tests, paving the way for commercial operation.

The journey from "Mikra" to the "New Railway Station" will be completed in approximately 24 to 26 minutes.
