rail track overview
Rail tracks serve as the foundation of railway transportation systems, providing a stable and secure pathway for trains to travel. Here's an overview of rail tracks:
Components of Rail Tracks
Steel Rails:
Steel rails are the primary components of rail tracks, providing a smooth and durable surface for train wheels to roll upon.
Fasteners:
Fasteners secure the rails to the railroad ties (sleepers), ensuring stability and preventing movement or displacement.
Railroad Ties (Sleepers):
Railroad ties, also known as sleepers, are rectangular supports that hold the rails in place. They are typically made of wood, concrete, or composite materials.
Ballast:
Ballast is a layer of crushed stone or gravel that sits beneath the railroad ties. It provides stability, drainage, and support for the track structure.
Underlying Subgrade:
The subgrade is the natural ground or prepared surface on which the railway track is built. It must be properly prepared to provide a stable foundation for the track.
