The term "permanent way" in railway refers to the physical infrastructure of the railway track, including the rails, sleepers (or ties), ballast, and other components that are designed to provide a stable and durable foundation for trains to run on.
The rails are the long metal bars that form the main running surface of the track, while the sleepers are the rectangular blocks of wood, concrete, or other material that are placed at regular intervals to support the rails. The ballast is the layer of crushed rock or gravel that is laid beneath the sleepers to provide drainage and stability.
In addition to these basic components, the permanent way also includes a range of other features such as switches and crossings, signals, and other safety systems that are necessary for the safe and efficient operation of the railway.
Maintenance of the permanent way is crucial to ensure the safety and reliability of the railway system. This involves regular inspections of the track and its components, as well as repairs and replacement of any damaged or worn out parts.
