Thebrake pressure was formerly 12,600 lbs.,now it is 30,000 lbs., or an increase of 138per cent. It has been suggested, he said, that thecast iron wheel is no longer equal to theconditions imposed by modern service andthat a remedy might be found in improvedquality of material. While this questionof improvement in quality is under con-sideration, Mr. Bush thought that possi-bly other developments might be broughtabout which would
