This book reports results of research on the characteristics of vehicles and response of the track structure on a series of curves, theoretical and experimental investigations, gives recommendations for the establishment of the shortest lengths of straight track between curves, and for allowable train speeds on such curves. Composed on an operational basis are instructions for layout of successive curves and the shortest lengths of intervening straight track on existing lines. The book is intended for scientific and technical engineering railroaders. Chapters are: (1) Curve layout; (a) Types of curves and their classification, (b) Requirements for arranging successive curves, (c) Allowable train speeds on curves; (2) Research on the response of rolling stock on curves: (a) Initial conditions and assumptions; (b) Acceleration of the vehicle on the transition, (3) Theoretical investigations into oscillations of cars occuring during movement through curves: (a) Research on roll of passenger car bodies on curves and establishing the amount of stabilization, (b) Research on freight cars, (c) Analysis of results; (4) Experimental reseach on trajectory of cars during entry and exit of curve transitions and design of this segment of the track; (a) Characteristics of test sections and units of rolling stock--methods of experimental research, (b) Experimental research results; (5) Experimental research on cars on series of test curves and the results: (a) Characteristics of test sections, vehicle characteristics and test procedures, (b) Methods of calculating test results, (c) Analysis of research results, (d) Results of observations on reverse curves and analysis of results; (6) Practical recommendations for allowable speeds and shortest straight track segments linking curves.
