Railway Track Components

There are some important Railway Track Components in the construction of railway track. The railway track is a permanent way for all trains. A railway track is a combination of rails, sleepers, ballast, and subgrades. The systematic rails fit on a number of sleepers. This sleeper rests on ballast supports by subgrades. These rails fix or welds together by a component name as fishplates.

The trach consists of two parallel rails fix at a specific distance. This distance depends upon the gauge of tracks. These rails are parallel to each other.

Railway Track Components

A Railway Track has many Components in it. they are as follows,

  • Rails
  • Sleepers
  • Ballast
  • Formations or subgrades

A good quality and strong aggregate materials, steel I section to use in the construction of railway tracks.

1. Rails

Rails are the first main element in the Railway Track Components. It is of an I section make with steel. Two rails fix opposite to each other. These rails are vertical I section elements places vertically throughout the track.  It lies parallel to the entire track. It carries the wheel load of trains providing them a smooth way. And transfer the load safely to sleepers.

2. Sleepers

Sleepers are concrete beds in the railway tracks. It is the second main important thing in Railway Track Components. Sleepers are of concrete, timbers, steel, cast iron, RCC, and prestress concrete. These sleepers fix vertical to each other. It fixes throughout the track. The main work of sleepers is to hold rails in a strong position. It receives the loads from rails and spread to ballast and subgrades.

3. Ballast

Ballasts are stone, aggregates, and gravels. these places below and around the sleepers. The main work of ballast is to hold sleepers and rails. And provides them a strong grip. Stone ballasts widely use in railway tracks in modern railways.

4. Formations or subgrades

These are natural soils on the bottom of a track. These are the foundations of tracks. It holds rails, sleepers, ballast and the entire track together. It supports the railway track from the bottom layer.
