SPECIAL COMMITTEE ON STRESSES IN RAILROAD TRACK. SEVENTH PROGRESS REPORT

Since 1914 this committee has conducted analytical and experimental investigations on the action of railroad track under the loads of locomotives and cars running at various speeds and for a variety of conditions. The tests herein reported were made to obtain information on the action of various types of rail joints in track when subjected to the loads of locomotives and cars at speeds up to 90 miles per hour. Testing equipment enabled tests to be made accurately and expeditiously in a way that had not been accomplished before. Tests were undertaken particularly to obtain information on the action of different forms of rail joints in track under the traffic of locomotives and cars running at various speeds and to learn the magnitude of the bending moments developed in the joint bars as compared with those developed in the full rail away from a joint. It was also desired to learn if possible how speed of train affects these various matters. To serve as a basis of comparison, the stresses and moments and depressions of the full rail in the same track under the action of the same locomotive and cars were needed. Tests were conducted at Elkton, Md. The test site was on a 14-min. curve to the right with superelevation of 1-1/2 in. Ahead of and behind this curve the compound curve became 33 min. The total curve extended over a distance of about a mile.
