A Study of a Corrugated Rail BY HENRY M. SAYERS M. I. E. E. (England) Despite the extensive literature dealing with rail cor-rugation, very little has been published to show pre-cisely how a corrugated rail is affected in its minutestructure. The disease has been studied from the pointof causation, but the symptoms of the suffering patient,, the rail itself, have not been investigated or put onrecord in any detail. It seems essential to the cure of such a trouble as railcorrugation that a full investigation should be made ofthe condition of the rail, so that as far as possible thenature of the failure of the material shall be ascer-tained, which may indicate the direction in which amodification of its mechanical properties should makeit more resistant. With this end in view a good specimen of corrugated. RAIL CORRUGATION—FIG. 1—CORRUGATED SURFACE OF RAIL rail, kindly furnished by A. L. C. Fell, chief officer ofthe London City Council Tramways, has been closelyexamined and photographed. The resulting photographswere used to illustrate Stephen Sellons paper on RailCorrugation and Its Causes, read before the Institu-tion of Civil Engineers, England. The rail came fromthe tramway on the Victoria Embankment, London. Ithad been in use thirteen months, corrugations had beenground out of it twice, the last time in October, 1913,and it was cut out for examination at the end of Janu-ary, 1914. It was the outside rail on a long-radiuscurve. By means of a straight edge laid on the rail table and feeler gages slid beneath in the hollows thedepths of the hollows were determined. The depth wasfound to be as great as in. in two places. Fig. 1is a face view, showing the characteristic appearance ofcorrugated rail, and also showing by the straight edgea marked det
