The Thessaloniki Metro has undergone recent operational developments involving both service impact studies and technical adjustments. An EKETA-IMET study conducted between late August and late September 2026 indicated that the expansion toward Kalamaia has reduced traffic volume by 2.5% to 8% and decreased travel times by up to 13%. Specifically, the Voulgari line saw an 8% decrease in daily traffic, while the 3rd of September line saw a 4.5% decrease.

Following these findings, the metro announced a temporary schedule change for Sunday, October 11, 2026, delaying service until 12:00 PM. This delay is intended to facilitate the final phase of integration testing for the two remaining train sets to ensure the full fleet can be incorporated into commercial operations. Additionally, scheduled maintenance at Nomarchia station will result in the temporary unavailability of the internal elevator on Sunday and Monday.
