What are the parts of the rail system?
A rail system's core parts include Rails, Sleepers (Ties), Ballast, and Fastenings, forming the track structure that guides trains; with larger systems also featuring Subgrade, Turnouts (Switches), and extensive Infrastructure like bridges, tunnels, and signaling, all working together for safe, smooth operation.
Core Track Components
- Rails: The steel beams that form the running surface, guiding the wheels.
- Sleepers (Ties): Support the rails and distribute the load onto the ballast.
- Ballast: Crushed stone providing drainage, stability, and a base for sleepers.
- Fastenings: Clips, spikes, pads, and plates that secure the rails to the sleepers.
- Subgrade: The prepared earth foundation beneath the ballast.
Main Types of Rail Fasteners
- Rail Joints: Connect individual rail sections.
- Turnouts (Switches): Allow trains to move from one track to another.
- Fish Plates/Splice Bars: Connect rails at joints.
- Track Pads: Rubber or plastic pads under rails or sleepers to reduce vibration.
GNEE RAIL is equipped with rail pad production lines for 130sets of machines, for the whole process of injection, refining rubber, sulfuration, moulding and inspection, etc. We own the most engineers for rail pad development, design, production and inspection, with annual production capacity reaching up to 2000, 000 pieces. What's more, rail pads for high speed rail lines are our featured products, including both the elastic rubber plates and height adjustment pads.

- Rail Anchors: Prevent rail movement due to thermal expansion and contraction.
Rail anchors vary in shapes, such as Improved Fair, Unit V or Channeled, with processing way of rolling, forging or casting. The latter two types are usually produced by casting, due to its complicated bending.
We produce different types of rail anchors to compromise different rail sections including 85LB, 90LB, 115RE, 132REm UIC54, UIC60, 50kg, etc.
