Permanent Way:

Definition

In railway engineering, the permanent way refers to the earthen formation and the track structure over it.

Gauge

The separation between the two rails of the track is known as the gauge. It is the distance between the inner faces of the two rails. In India, it has been decided to have one gauge, the broad gauge (BG). The gauge dimension is 1.676 m.

Cross Section of a Track

A typical cross-section of a broad gauge (BG) track is given in Figure.
