Solutions
Despite heavy Gaziantep traffic, construction continued uninterrupted. Phased commissioning allowed completion with minimal impact on city life.
Sustainability
Environmental Management
Electric infrastructure reduced carbon emissions.
Shifting traffic from city roads to suburban rail reduced fuel consumption and air pollution.
The cut and cover tunnel removed the urban barrier effect and maintained continuity of the urban fabric.
Social Impact and Participation
Safe, comfortable daily transport for hundreds of thousands improved quality of life.
Domestic trainsets supported the national economy and technology manufacturing.
Fast transport between industrial areas and the center facilitated workforce mobility.
Long Term Contributions
Targeting 350,000 passengers daily, it will reduce private car use and contribute to sustainable city life.
Domestically manufactured trainsets support technology development and national production capabilities.
Future phases are planned to integrate Gaziray with Gaziantep Airport and BÜSEM.
Modernization of the existing suburban line created a high capacity system serving urban and suburban transport.
