W21 – Rail Fastening System

YHT RAY BAĞLANTI SİSTEMİ

W21 rail fastening system is designed to work with high speeds and vibration in the ballasted railways.

It is generally used with the B07 concrete sleepers on the railways which high-speed trains cruises.

Current rail pads have the characteristics to stand over high-level vibrations and provides comfort for the train cruises. It successfully satisfies the required axle loads, speed and vibrations.
