MEASUREMENT OF STRESSES IN 115 RE RAIL ON TANGENT TRACK--NORTH WESTERN RAILWAY

The test sections for the new 115 RE rail includes 100 joints and is approximately 2000 ft. long. The test section was installed for the purpose of testing various joint bar designs. The maximum tension and compression stress are shown during each test run obtained at one joint with the new spacing (3-1/2-6-6 in.) and another joint with the two hole spacing (4-1/2-9 in.) on the north rail. The chart shows the stresses for diesel and steam locomotives separately, and also those developed under cars. Values are plotted with respect to the speed of the train. The new 115 RE rail design on tangent track with either of the bolt hole spacings has sufficient fatigue strength to resist development of fatigue cracks, provided no unusual corrosion conditions exist.
