From these reservoirsthe air passes by a pipe througli a reducing valve into a smallreceiving tank at a pressure of 50 lbs., more or less, accordingto the size of the car and the consequent power required foroperating the brake. In some cases a pressure of 25 lbs. isamply sufficient. From this receiver the air passes throughpiping to the motormans valve, where it is under the controlof the motorman and can be used to put the brake in opera-tion and to release the brake to its normal position. From the motormans valve the air passes into pipingwhich connects with the brake cylinder. To operate the brake. The installation of the Magann air brake does not in anyway interfere with the operation, in case of need, of the ordi-nary hand brake, and the cars can still be equipped with ahand brake, though experience shows that there is practicallyno necessity for this, owing to the simplicity of the apparatusused, which reduces to a minimum the likelihood of its gettingout of order. A duplex gage, placed in front of the motor-man, shows the pressure of air, both in the reservoir and thereceiver, so that he is fully advised as to the amount of airstill available for use on his car before the reservoirs requirerecharging.
