Athens Metro Trainset Modernised

Why It Matters

Extending the fleet’s lifespan and improving capacity strengthens Athens’ commuter network while deferring costly new‑train purchases, supporting Greece’s transport modernization and EU sustainability goals.

Key Takeaways

• CAF refurbishes 14 Athens metro trainsets, first Greek contract
• €70 million ($76 million) upgrade replaces DC with AC traction
• Interiors now include accessibility zones, LED lighting, CCTV
• Service life extended by ~25 years, enabling higher frequencies
• Full fleet delivery slated for May 2027

Pulse Analysis

The Athens Metro’s Line 1 has relied on a fleet of MAN/Siemens EMUs built between 1983 and 1985. After more than four decades of service, the rolling stock showed signs of wear and lagged behind modern standards for energy efficiency and passenger comfort. In 2022, STASY awarded a €70 million (approximately $76 million) contract to Spanish rail‑equipment manufacturer CAF, marking the firm’s first major procurement in Greece. The agreement covers a complete refurbishment of all 14 trainsets, with the first unit already delivered back to service.

The refurbishment replaces the original DC traction system with CAF Power & Automation’s AC drives, delivering higher reliability and lower energy consumption. Auxiliary equipment, braking and door‑control mechanisms have been modernised, while the interiors receive a comprehensive overhaul: dedicated spaces for passengers with reduced mobility, new LED lighting, upgraded air‑conditioning, real‑time passenger information displays and CCTV surveillance. These upgrades not only bring the trains in line with EU accessibility directives but also enhance the rider experience, reducing dwell times at stations and supporting smoother, more frequent service.

By extending the fleet’s service life by roughly 25 years, the programme defers the need for a costly new procurement and allows STASY to increase train frequencies on the busiest commuter corridor in the capital. The May 2027 completion target aligns with Greece’s broader transport modernization agenda and the European Union’s push for greener, more efficient public‑transport networks. CAF’s involvement also showcases the growing role of Spanish rail manufacturers in Southern Europe, positioning them as key partners for future infrastructure upgrades across the region.
