FIELD: railway transport; service facilities.
SUBSTANCE: proposed water column has hydrostatic pressure transmitter 9 whose output signal is proportional to level of empty part of tank 2 under filling, comparison, signaling and interlocking unit 11, and control unit 13, all equipped with input and output data remote transmission devices, operating device 3 for switching hydraulic channels containing operating mechanism, and pushbutton selector switch and magnetic starter 5 with interlock circuit placed in operating mechanism control circuit. Operating mechanism is connected with regulating member equipped with three-way valve 7. If magnetic starter is de-energized, tank to be filled can be connected with transmitter 9 through open passage of three-way valve 7 to check level of empty part of tank, or when magnetic starter is switched off it can be connected through three-way valve to outlet branch pipe of water supply ON/OFF operating device.
EFFECT: reduced consumption of water.
