Ikon Yapı took part in the Yerköy–Sivas Safety Tunnels Project within the Ankara–Sivas High-Speed Railway Line. Covering 26 escape tunnels with a total length of approximately 15,932 meters, this critical infrastructure investment required high-performance safety solutions. We implemented high-pressure-resistant Teckentrup tunnel doors designed to ensure safe evacuation of passengers and technical staff in emergency scenarios. Engineered for heavy-duty conditions and stringent safety requirements, our solution contributes to operational continuity and enhanced safety within railway tunnel infrastructure.
