FOUR BOLTS VERSUS SIX BOLTS IN JOINT BARS FOR 155-LB., 140-LB., AND 133-LB. RAILS--JOINT BARS TO BE STANDARD LENGTH

Four different punchings of bars with compatible rail drillings were compared at three test locations. All the bars used were of standard length and design, the only difference being the hole location. The test was laid out in such a manner that measurements of batter and deflection of joints could be obtained on both tangent and curved track. The curve was 1 degree 52" in the portion of the 140-lb. test rail with AREA drilling, four hole special drilling, PRR standard drilling, and PRR standard with second hole from each end omitted was laid on tangent track only. There is no material difference in profile or in maintenance cost among the various combinations tested. The four hole bars tested will adequately fasten the rail, but the saving realized by elimination of two bolts would not be enough to justify the expense of the change of standard.
