STRESSES AT RAIL JOINTS AS INFLUENCED BY BOLT HOLES

The failures of rails caused by bolt holes of joints (end breaks) have recently come to occupy the majority of rail breaks. In order to prevent such breaks it was customary to reduce the diameter of the bolt holes or to keep the holes away from the rail ends. The present writers conducted experiments upon joints of the structure actually used for 50 kg/m rails, bolts of different diameters, rails with bolt holes of different intervals and fishplates with bolt holes of different diameters and different intervals with an aim of ascertaining what type of a fish joint is the most durable.
