METHOD OF TRAIN SEPARATION Russian patent published in 2011 - IPC B61L1/16 

FIELD: transport.

SUBSTANCE: invention relates to railway ACS and telemetry systems and may be used for train separation in station limit with automatic interlocking systems. Station limit is divided into block-sections equipped with rail circuits for control of their state and signal lights continuously receiving and processing data coming from advance signal section on the state of advance block section and cutting on appropriate signal light to continuously send data to rearward signal light. With no trains on station limits signal lights are de-energised, while with trains on said station limits four advance signal lights are energised. Fourth signal light generates and transmits data on occupancy of guarded block-section. Third, second and first signal lights receive and process data from advance signal light to transmit said data on guarded block-section state to signal light located rearward of signal light, and to switch on appropriate signal at signal light that is located first block-section ahead of the train.

EFFECT: higher capacity of station limit and traffic safety.
