What are rail parts?
Rail parts are the essential components of a railway track system, including rails, sleepers (ties), fasteners, ballast, and the underlying subgrade, all working together to create a smooth, stable, and safe pathway for trains to roll on, transferring immense loads from the train to the ground. Key parts include the steel rails (providing the surface), sleepers (supporting rails and spacing them), ballast (stability, drainage), and fasteners (clips, pads, bolts securing everything).
Core Components
- Rails (Steel Rails): The main I-beam shaped steel sections that guide train wheels, providing a smooth, durable surface.
GNEE RAIL are available to produce steel rails of various standards used in coal mining, main railway lines, factories, cranes, etc. There are light steel rails, heavy steel rails, crane steel rails, and over heavy steel rail.

- Sleepers (Ties): Horizontal supports (wood, concrete, steel) placed under rails to hold them at the correct distance and distribute load to the ballast.
The railroad tie is always laid perpendicular to the rails, used to hold the rail upright and keep it spaced to the correct gauge.
- Ballast: Crushed stone bed under sleepers, providing drainage, stability, and load transfer to the subgrade.
- Subgrade (Formation): The prepared ground beneath the ballast, forming the foundation of the entire track structure.
Rail Fastening for Track Rail
Rail fastenings are crucial components that secure rails to sleepers (ties), providing stability, maintaining correct gauge, and absorbing train impacts and vibrations for safe, smooth operation, using various parts like spikes, clips (e.g., E-clips, Deenik clips), bolts, and plates to withstand vertical, lateral, and longitudinal forces, while offering elasticity and preventing displacement.
- Rail Spikes: Large nails (e.g., cut spikes) used to fix rails or baseplates to timber ties.
- Rail Clips (e.g., E-Clip, Deenik Clip): Spring steel clips that clamp the rail to a baseplate, providing elasticity.
- Screw Spikes/Track Screws: Used with baseplates, especially on concrete sleepers, for secure fastening.
- Baseplates/Chairs: Sit between the rail and sleeper, often canted (angled) for correct rail inclination (cant).
- Fish Plates: Connect rail ends together.
- Bolts & Nuts: Used for various connections, including fish plates and securing components to girders.
