Functions of a Railway Fastening System

Holds the rail firmly in place, preventing lateral and longitudinal movement.

Distributes the load from the rail to the sleeper and ballast, reducing stress on individual components.

Absorbs vibrations and shocks caused by train movements, reducing noise and wear.

Maintains proper track alignment and gauge, ensuring smooth and safe train operations.

Prevents electrical conductivity between the rail and sleeper, essential for signaling systems.

Accommodates thermal expansion and contraction of the rails due to temperature changes.

High-quality materials and designs ensure long service life (20–30 years).

Elastic properties minimize wear and tear, lowering maintenance costs.

Secure fastening reduces the risk of derailments and track failures.
