Railway track (new) showing traditional features of ballast, part of sleeper and fixing mechanisms

The permanent way is the elements of railway lines: generally the pairs of rails typically laid on ties ("sleepers" in British parlance) embedded in ballast, intended to carry the ordinary trains of a railway. It is described as permanent way because in the earlier days of railway construction, contractors often laid a temporary track to transport spoil and materials about the site; when this work was substantially completed, the temporary track was taken up and the permanent way installed.
