Permanent Way and Its Members

The principal function of the permanent way is accepting the imposed dynamic and static loads as cars, locomotives and trains travel over the track.                                                                                                                                

All elements of the permanent way must be strong and durable in railway operation in order to ensure the safety of travel. The maintenance of the permanent way must be cheap and besides it must have a long service life.

The railway construction with all its problems of track construction, ballasting jobs and so forth, is primarily an engineering problem. Permanent way is the important structure which interacts with the rolling stock providing railway traffic.

The railway track of today is quite different from that used in the early days of railways. The first track had no ballast, the rails were made of wood and rested on heavy blocks of granite. But in general the modern railway track is not greatly different from that of a hundred or more years ago. As then, it consists of two parallel rails, supported on and fastened to sleepers which are laid on a suitable material known as ballast. It's the foundation of the railway which holds the track in line and provides needed drainage.

The rails differ greatly in weight according to the kind of traffic, which they have to carry. The largest and heaviest rails are laid in the main-line tracks for it is those tracks which carry the largest volume of traffic.
