EIGHTH PROGRESS REPORT OF THE SHELLY RAIL STUDIES AT THE UNIVERSITY OF ILLINOIS

Two rails were selected from the high side of a 4-deg curve. These rails had carried 63,385,600 tons of traffic at average speeds of 35 mph. One rail showed flaking along the gauge corner over its entire length and had also developed 6 or 7 small black shelly spots. The second rail contained 30 black shelly spots. During the past year, 23 specimens have been tested in the cradle type rolling load machine. The chemical analysis, physical properties and results of rolling-load tests of these specimens are shown. The laboratory rolling-load tests produce shelling failures similar to the deeper type of shelling which develops in service. It is also believed that the laboratory tests give a quick method of determining the relative length of service which can be expected in track as compared with standard carbon steel rails. Preliminary results of service tests of rails tested in the rolling-load machines last year give indications of this correlation but the service tests are not as yet completed.
