Description:

As per reports, metro operator STASY (Urban Rail Transport Company) announced on Wednesday (03 December) that Metro Line three is temporarily operating only between Dimotiko Theatro and Ethniki Amyna due to a power supply failure affecting the Holargos–Doukissis Plakentias section.

• The service interruption began in the afternoon hours around 1520 hours local time (1320 hours UTC), with the fault causing immediate suspension of operations along the northern stretch of Line three, impacting passengers travelling toward Holargos, Agia Paraskevi, Nomismatokopio, Halandri, and Doukissis Plakentias.
• The metro disruption coincided with widespread power outages in northern suburbs, including Maroussi and Kifissia, contributing to broader mobility difficulties across the metropolitan area.
• Technical teams were deployed to identify the source of the power disruption and restore service as quickly as possible, ensuring the safety and stability of the electrical system before resuming train circulation.
• Further updates on the restoration timeline were expected following full diagnostics and confirmation that all operational safety standards had been met.

Impact:

• Passengers travelling on Metro Line three may experience extended travel times and inconvenience as services are limited to the Dimotiko Theatro–Ethniki Amyna section, reducing direct access to northern suburbs.
• Residents in affected areas such as Holargos, Agia Paraskevi, Halandri, and Doukissis Plakentias may need to shift to buses or private vehicles, increasing overall commute duration.
• Power outages in northern suburbs including Maroussi and Kifissia may affect business continuity for retailers, offices, and service providers.
• Public transport congestion may increase across unaffected metro lines and bus routes as displaced commuters seek alternative travel options.
• Delivery and courier services operating within Maroussi, Halandri, and surrounding areas may encounter delays due to transport disruptions and variable traffic conditions.
• Increased road traffic in northern suburbs may lead to slower movement on key routes such as Mesogeion Avenue and Kifisias Avenue as commuters avoid the metro.

Recommendations:

It is advised to monitor official transport announcements, plan additional travel time, and make use of alternative routes until normal service on Metro Line three is fully restored.
