The Nabla rail blade is also called Nabla rail clip. It is a specialized spring steel blade used in the "Nabla fastening system," a type of railway track fastening system commonly used in Europe, particularly for tram, metro, and high-speed rail lines; the unique shape of this blade creates a stable toe load on the rails when tightened, ensuring secure attachment to the sleeper (tie)
On the fatigue life, when the deflection is 9.1mm,they can provide a performance of 5 million cyles without crack.
