MEASUREMENTS OF STRESSES IN 132 RE RAIL ON TANGENT TRACK--SANTA FE RAILWAY

Three test sections are as follows: new AREA design, headfree 36 in. joint bar for 132 RE rail, with bolt spacing of a 3-1/2--6--6 in.; same joint bar design with bolt spacing of 4-1/2--9 in.; and same joint bar design with bolt spacing of 2-1/2--6-1/2--6-1/2 in. This installation offered an opportunity to obtain measurements of stresses developed under regular traffic in the new 132 RE section. On tangent track under conditions typical of main line operation, it may be concluded: that the stresses in the upper rail fillets on tangent track outside of the joint bar limits have been reduced with the new 132 RE section to well within the fatigue strength of rail, steel, and that the concentrated rail web stresses within joint bar limits at the rail end and at the first bolt hole with the new 132 RE rail section and the new AREA bolt spacing are well within limits that can be tolerated, provided no unusual corrosion conditions exist that substantially reduce the fatigue strength of the rail steel.
