GUIDING PRINCIPLES FOR THE DESIGN OF POINTS AND CROSSINGS

Accelerations were analyzed with reference to comfort in passenger bogie coaches and two locomotives were used to ascertain the effects of the guide force on wear and fatigue of the switch fittings. The object of these studies were to discern the influence of the following factors on accelerations and forces at various speeds: size of the angle of impact; radius of curvature of the turnout; transverse stiffness of the track; and characteristics of the vehicle suspensions. An analogue computer and a digital computer were used for making the calculations. Results of the calculations are shown.
