RUNNING SAFETY OF VEHICLES FITTED WITH THE AUTOMATIC COUPLER. SURVEY PROBLEMS--PRESENTATION OF QUESTIONS COVERED

This report states the reasons which led to the study of Question B 125, though its principal subjects are the problems concerning the safety against derailment of wagons equipped with the automatic coupler. The results obtained using the calculation methods of the B 125 Specialists Committee are discussed. The set of diagrams being prepared for UIC Leaflet 530-2 is explained and clearly illustrated with the aid of some diagrams. The problem of "passenger coaches in a freight train" is treated, and indications are given for the calculation of the permissible longitudinal compressive forces for specified types of wagon.
