Giant 'Triangle Interchange' to Turkey's lifeline

Osmaneli, a district in Bilecik province—the birthplace of the Ottoman Empire—is set to become the junction hub for Turkey's high-speed rail network through a connection known as the "Müselles Hat" (Triangle Line), linking Bursa to the Ankara-Istanbul high-speed rail corridor. The project positions the district at the center of one of the Republic's most significant infrastructure undertakings, turning it into a critical node where multiple high-speed lines converge. The Müselles Hat connection would integrate Bursa, currently outside the main Ankara-Istanbul high-speed route, into the national network via Osmaneli. The development matters because it could reshape regional transport connectivity and elevate a small Anatolian district into a strategic logistics and passenger transit point. What to watch next is the project timeline and construction progress, along with how the junction affects rail capacity on the Ankara-Istanbul line.
