Cuenot. It was found that when the firstwheel of the engine is about 20 feet from a tie the upward movement commences and reaches a maxi-mum at about 10 feet. 224 STEEL RAILS The observations of the depression of the roadbed made in these experi-ments are of importance. On cinder ballast that part of the roadbed in whichthe stakes were driven (31 inches from the track) was depressed a maximumof .049 inch and on gravel ballast the maximum was .036 inch. Wooden stakes and iron bolts were drivendifferent depths into theroadbed with similar re-sults; in f
