Text-book on Railroad Surveying
THIS book gives a fair representation of American practice in railroad surveying. The subject-matter includes brief directions for carrying out the preliminary reconnaissance in various types of country, and the location of the best route. Fuller explanations follow of the setting out of circular and spiral transition curves; this section includes turn-outs, connections, and crossings. Earthwork problems are also treated. Methods are explained of shifting the location of curves in the field from that shown on the plan in order to secure better conditions of cutting or filling. The text occupies 125 pages, and the remaining 138 pages are taken up with tables giving curve functions, logarithms of numbers, trigonometrical functions of angles and earthwork. Detailed mathematical solutions are omitted, and an elementary knowledge of surveying is assumed. Judging from the terse nature of the contents, the title “Pocket-book of Railroad Surveying” would probably be more appropriate, and would convey to engineers the fact that the book will be found to be a useful companion in his field operations.Text-book on Railroad Surveying.By G.
