STRESSES IN THE RAILS, IN THE BALLAST AND IN THE FORMATION RESULTING FROM TRAFFIC LOADS. TRACK MEASUREMENTS OF STRESSES IN RAIL FASTENINGS

Interim Report No. 3, prepared by the D 71 Committee, gave the results of a series of laboratory tests carried out on several types of German, British and French fastening. The present report gives the results of field measurements taken using the same types of fastening. Measurements of the British fastenings were limited to ascertaining the transverse stiffness (section 2). Three particular features were measured: 1) measurements of the gauge widening of the unloaded track due to a given horizontal force pressing the two rails apart; 2) measurements of the forces exerted by the wheel of a vehicle on the rail; 3) measurements of the variation of the holding-down force of the coachscrews with passing trains.
