Book excerpt: Excerpt from Notes on Permanent-Way Material, Platelaying and Points and Crossings The permanent-way inspector of to-day so far as my knowledge of him goes is not merely that vague product, a "practical man;" he does not necessarily prefer guesswork to certainty; he has not a supreme contempt for a simple and intelligible mathematical method; he has not a serene confidence in the fallible process of "putting it in by the eye;" and he is not one jot less practical than the platelayer of the old school, although he has had the advantage of a better education. To him, then, I dedicate this little book. The first chapter deals with the material which the platelayer has to work with. While on furlough in 1885 I was engaged for some months in passing material for the War Office, and so had constant opportunity of observing the processes of manufacture which I have briefly described. The inspection and test reports, I may add, are quotations from my own papers. In the second chapter I have described the actual operations of platelaying, both as regards construction and maintenance; and for assistance in this portion I am greatly indebted to Inspector Campion and several other friends, both Engineers and Platelayers. The third chapter treats of points and crossings. Upon this subject Donaldson is, without question, the great authority. But simplifications of his treatment follow at once from the measurement of the gauge from inside edge to inside edge of rail-head, instead of from centre to centre of rail, since the width of the upper table of the rail disappears from all terms of the calculation, and only affects the clearance.
