The Istanbul Halkalı Ispartakule Railway Project is a significant infrastructure development aimed at enhancing the transportation network in Istanbul, Turkey's largest city. This project involves the construction of a high-capacity railway line designed to improve connectivity between the Halkalı and Ispartakule regions, two critical parts of Istanbul's rapidly growing urban and suburban areas. The project is part of Turkey's broader efforts to modernize its transportation infrastructure and facilitate seamless travel within the city and beyond.

Unicrane has supplied 10 sets of universal ring molds with the specification OD 8.2m × 1.6m × 0.4m (6P/R), which are crucial for the production of high quality tunnel segments for this project.
