Recent developments affecting rail sections were discussed. Tests made at the Area Research Center of a 115-lb rail in which holes had been punched with a velocity power punch showed that the fatigue strength of the specimen was higher than that of a specimen in which the holes had been drilled. However, cracks developed in service rail on which this tool had been used. Further testing was done, and it was concluded that an improved velocity power punch must be manufactured.
