FIELD: transport.
SUBSTANCE: invention relates to railway automatic hardware to be used in signaling, centralisation and interlocking circuits at railway transport facilities, in particular, in devices intended for train separation at spans and stations. Proposed device comprises unit to receive amplitude-modulated signal with its input making that of device proper and its output connected with input of signal nonlinear processing unit, amplifier and track relay connected to its output. It includes OR element and unit of signal spectral processing unit with its input connected to aforesaid amplitude-modulation signal receiver unit output. OR element first and second inputs are connected to output of nonlinear processing unit and that of spectral processing unit, respectively, while OR element output is connected to amplifier input.
EFFECT: higher reliability and noise immunity in operating frequency range.
