On May 29, the last shutdown of the Thessaloniki Metro main line is expected, barring an unlikely event, lasting about 2.5 weeks.

This will be the final stage of testing before the launch of the extension to Kalamaria, with the goal of completing the project by the end of July.

When the Metro will close and for how long

As Deputy Minister of Infrastructure Nikos Tachiaos reiterated, the main line will be shut down on May 29 to complete critical integration tests with the new Kalamaria line.

The shutdown will last approximately two and a half weeks, and according to him, the aim is to avoid any further closures until the project is completed.

Extension to Kalamaria by the end of July

Tachiaos noted that the main objective is to complete the extension by the end of July, highlighting the technical complexity of the project.

As he explained, the extension is a branch of the main line, requiring higher safety standards and complex certification procedures, while testing is being carried out while the Metro remains operational.

“The systems must be certified, which is not easy and takes time,” he said.

How the two lines will operate

Once the extension is completed, the Thessaloniki Metro will operate two lines with a total of 18 stations.

The two lines will share the first 11 stations, from the New Railway Station to 25th March.

From that point:

– The main line will continue toward Voulgari and Nea Elvetia

– The Kalamaria line will run to Mikra, via five new stations

What changes in tests and schedules

After the main line reopens, the trial operation phase will begin.

Gradually, toward the end of June, services will start operating on both lines:

– New Railway Station – Nea Elvetia

– New Railway Station – 25th March – Mikra

During the transition phase, trains to Mikra will terminate at 25th March for passengers and continue without passengers for testing.

Passengers will need to choose their route carefully, otherwise transfers will be required.
