The train pipe pressures withall of the reductions that were made init, as well as the brake cylinder pres-sures, and train speeds were and without the inter-vention of the attendant. The tests were made on regular runsof a milk train between Sidney andMiddletown in order that the recordsmight be made from work on the ruadand thus an average of efficiency be ob-tained that would correspond to whatcould be expected in every day SAUVAGE BRAKE IN FUl,!. RELEASE. the cylinder. This is one of the rea-sons why pressures that seem to be somuch above the standard of 70 percent, can be used without any appar-ent injury to the wheels. The application that has been madeof this brake to these milk cars has ta-ken this into account, but even thentlie percentage of full pressure is ex-ceedingly high, yet it has been usedsuccessfully and satisfactorily. In fact,the brake is used untouched on bothlight and loaded cars with no bad ef-fects either on the wheels, the brakerigging or the trucks. The control thusafforded in the handling of the trainmakes it possible to run at high speeds,even down the heavy grades withwhich the road abounds, with perfectsafety and assurance that the train canbe stopped within reasonable limits. In order to ascertain just what couldbe done and make a comparison be-tween the efficiency of the brake as
