DEVELOPMENT OF HEAVY RAIL-PROFILES. STUDY OF A NEW 71 KG/M RAIL (ORE 71 PROFILE)

The guiding principles for the study of heavy rail-sections already having been defined in a previous report (D 120;RP 1), calculations have been carried out on three heavy rail-sections with a view to defining a new rail of approximately 70 kg/m. Two of these sections represented a synthesis of 10 preliminary rail-section designs and would have to be compared with a third one chosen by way of reference (140 1B AREA American rail). The results of the calculations and the rolling conditions have finally enabled a new rail of 71.27 kg metric weight to be proposed.
