Halkali - Istanbul New Airport Metro Line

This project reference encompasses the complete mechanical works, including key stations and auxiliary structures at Kayaşehir, Olimpiyatköy, and Fenertepe, along the Halkalı–Arnavutköy section of the Halkalı–Istanbul Airport Metro Line. As the final 22-kilometer segment of the 69-kilometer Gayrettepe–Istanbul Airport–Halkalı ring line, this section serves five stations and establishes crucial network integrations with the M3 Bakırköy–Kirazlı line at Kayaşehir and the M9 Ataköy–İkitelli line at Olimpiyatköy. Operating at speeds up to 120 km/h, the line delivers a high-capacity transit solution capable of moving 36,000 passengers per hour per direction.
