Synopsis
Methods Of Location: Or, Modes Of Describing And Adjusting Railway Curves And Tangents, As Practised By The Engineers Of Pennsylvania by Samuel Wright Mifflin. Originally published in 1837, the work assembles Euclidean propositions and a suite of location techniques that rely on the Transit and a standard chord unit. It explains how curves are described on the ground, how central, circumferential, and tangential angles relate, and how to construct and adjust compound and reversed curves, as well as how to join curves to tangents with precision. The text provides step-by-step procedures for measuring angles, changing the origin of curves, and drawing tangents, with emphasis on field usability and memory-friendly methods rather than heavy calculations or tables. The Preface notes collaborative contributions from Pennsylvania Railway engineers and the author’s aim to produce methods that can be executed in the field, even if the book is left at home.
