FIELD: machine building; rail vehicles.
SUBSTANCE: invention relates to railway transport braking systems. Railway rolling stock brake line density control device contains the main tanks with the locomotive feed line connected, to which the engineman crane with the controller is connected, connected to control unit, which is equipped with memory unit, signalling unit, measurement control elements and element for connection of movement speed measuring devices. Device is additionally equipped with a controlled shut-off valve connecting the feed line to the control circuit reservoir, through which the feed line is connected to the control circuit main line and the auxiliary compressor. Controlled shut-off valve is connected to the control unit, which is also connected to another controlled shut-off valve, through which the feed line of the leading section of the train is connected to the feed line of the second and subsequent sections of the locomotive.
EFFECT: ruled out depletion of train brake line and leakage from feed line via control circuits.
