The NABLA C1 Fastening System is a robust, standard railway component used to securely attach rails to sleepers (ties), providing essential stability, vibration dampening, and precise alignment for heavy loads and high-speed trains. It's a type of elastic fastening system, featuring the distinct NABLA C1 clip (a spring steel fastener), insulators (guide plates), rail pads, anchor screws, and washers, designed for reliable performance and easier maintenance on various track types, from metros to high-speed lines.

What are the main differences between Nabla RNTS and RNTC?
The main differences between the Nabla RNTS and Nabla RNTC rail fastening systems center on the type of sleeper they support and their internal assembly components. Both are classic STEDEF (Sonneville) fastening systems designed for noise and vibration reduction.
While both are STEDEF fasteners, the RNTS is used for flat sleepers and requires a cast-iron base plate, whereas the RNTC is designed for profiled (sloped) sleepers and typically uses rail insulators directly.[...]
