Permanent Way (history)
The permanent way is the elements of railway lines: generally the pairs of rails typically laid on the sleepers ("ties" in American 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.

Famous quotes containing the word permanent:
“The pork sizzles and cries for fish. Luckily for the foolish race, and this particularly foolish generation of trout, the night shut down at last, not a little deepened by the dark side of Ktaadn, which, like a permanent shadow, reared itself from the eastern bank.”
—Henry David Thoreau (18171862)
