A. Carney, Master Mechanic of the St. Louis Division,and Mr. M. H. Wickhorst, Engineer of Tests. This work resulted from discussions with train and enginemen with regard to the use of the rail washer, the men claim-ing that it would make a decided difference in the ease withwhich heavy trains may be pulled over grades, and especiallythose involving curvature. Preliminary experiments weremade in the Galesburg yard to determine the effect of therail washer, and it was found that its advantage was so slightupon a heavily sanded rail and a straight, approximately leveltrack that it did not at that time appear to warrant the intro-duction of the device on main line engines. The claim was. Curves on Arenzville Hill made by men on the St. Louis Division that by wetting the raillubrication is provided to a certain extent, reducing the flangefriction on curves. The almost unanimous opinion resulted indynamometer tests to settle the question. The object of the tests was to determine the difference intrain resistance when sand was left on the rails after the pass-age of the engine, and where the sand was washed off behindthe drivers with a rail washer, which consists of a pipe tappedinto the boiler below the water level, with a branch extendingto each rail so that the sand may be washed off by a streamof hot water and steam under the control of suitable dynamometer car, which is a part of the equipment of thisroad, was used and the trials were made on October 31 onArenzville Hill, on the St. Louis Division, where the desiredtrack conditions were found. The hill was staked out in 14sections, each 500 feet long. One of the engr
