Elastic bearing of the Ankara – Sivas high-speed line

The ‘Middle Corridor’ along the New Silk Road connects Türkiye with Georgia and Azerbaijan. Between the capital Ankara and the city of Sivas in the Central Anatolia region, the Turkish railway company TCDD has built a new, double-track high-speed line for passenger and freight services as part of this corridor.

The challenge

Very high number of transitions into tunnels and onto a bridges
Speeds of up to 250 km/h
High requirement for track availability

The Getzner solution

Around 350,000 m² of under ballast mats and about 150,000 under sleeper pads were used to protect the superstructure. Mass-spring systems provide optimum vibration protection on 20,000 m² of slab track.

Railway construction site with ballast, sleepers, and rails set against a city skyline.

Advantages for customers

Lower maintenance costs thanks to reduced wear
Increased safety and availability by protection of the superstructure
Higher acceptance due to efficient vibration protection

The elasticity of the Getzner products brought the stiffness of the tracks to the desired level. Our goal is to significantly reduce maintenance costs.
