The work and the technique: Thessaloniki Metro System, Greece

The construction and development of the Thessaloniki metro line involves a single line that runs throughout the city. In addition to building 13 modern stations, the project includes the supply of rolling stock, consisting of 18 modern, fully air-conditioned, automated trains. Other key components include installations for line works, a 50,000 m² depot for rolling stock complete with a workshop for the maintenance and repair of mechanical and electrical equipment, and the development of two junctions for future extensions of the metro. The project also encompasses staff training.

Located within the same area as the depot is the operational and control centre for the new line and the administrative offices of Thessaloniki Metro.

Excavations were carried out using the NATM (New Austrian Tunneling Method) for 118 meters, two TBMs (Tunnel Boring Machines) for 14.6 kilometres, and the Cut & Cover method for 1 kilometer. In total, 2,442,238 cubic meters of materials were excavated, with 607,222 cubic meters of concrete and 68,938 tonnes of reinforcing steel used.

With the new Thessaloniki metro line, it is estimated that there will be a reduction of 22,000 tonnes of CO₂ emissions per year and approximately 150,000 fewer cars on the road each day.
