Therestoration of the pressure within thebrake pipe released the brakes and re- charged the reservoir. This developmentoccurred during 1872 and 1873. The automatic brake was at that timesupposed to be instantaneous in its actionin applying the brakes, and almost in-stantaneous in releasing them.

The automatic brake having proveditself vastly superior to the plain orstraight air brake first described, it soonbecame a standard, but during the transi-tion period an automatic brake waseasily converted into a plain brake by amanually operated special valve arrangedin the casing of the triple valve. The gradual increase in the length offreight trains and the numerous accidentsdue to lack of brake control early sug-gested that automatic air brakes shouldbe made a part of the equipment of allfreight trains, and, to determine the prac-ticability of the automatic brake for thispurpose, a train of fifty cars was fittedin the early eighties and taken over theAlleghenies on the P
