Nabla Rail Fastening System

Nabla Rail Fastening System
The Nabla Rail Fastening System is an advanced and robust rail securing solution developed for high-speed, heavy-haul, and mixed traffic lines. It is primarily used with concrete sleepers and has been widely adopted across European, African, and Asian railway networks.
The system is composed of Nabla-shaped clips, screw spikes, insulating bushes, and rubber pads, offering strong rail restraint and excellent elasticity. Its design provides superior resistance to lateral and longitudinal movements, as well as outstanding fatigue performance under high-frequency load conditions.
Key Features
High clamping strength: Maintains track geometry under high-speed and heavy-load conditions.
Excellent fatigue resistance: Ensures long service life with minimal component wear.
Good electrical insulation: Suitable for signal track zones and electrified sections.
Compliant with EN and UIC standards: Certified reliability for international railway projects.
Typical Applications
High-speed railways
Freight and heavy-haul lines
Ballastless and mixed-traffic tracks
Turnouts and transition zones
