KFS SIL2*: Signal Crossing Prevention System
(ATS - Automatic Train Stop)

General Presentation

 

 

 

 

 

KFSI Beacon (Integrated Signal Crossing Prevention)

The analogical KFSI Beacon is an integrated autonomous device for electrical and thermal railway systems (train/urban subways/RER/tramway).

Its main function is to provide information on a crossing at a traffic signal (red light/green light). It is installed on a ballast between the tracks via the intermediary of an external chassis with anti-vibration resilience.

The electrical equipment attached to the traffic signal provides the Beacon with red light information (which is the same when there is no light) or green light information.

A permanent magnet creates a constant magnetic field. The presence of this magnetic field alone informs the onboard sensor and its treatment block that the Beacon, in other words the related traffic light (red light or no light), must not be crossed.

When the light is green, this magnetic field runs in parallel to the electro-magnetic emission of two F1 and F3 frequencies, informing the onboard sensor and its block of an authorization to pass.

Three Beacons are available:

  • The KFS mp Beacon (anti-signal crossing prevention device for the Paris subway system) is a functional equivalent of the RPS permanent magnet Beacon used on the urban subway system in Paris.
  • The KFS rp Beacon (anti-signal crossing prevention device for the Paris RER) is a functional equivalent of the RP electromagnet Beacon used on the RER system.
  • The KFSI Beacon (integrated anti-signal crossing prevention device) is a functional equivalent of the RPS subway and RER Beacons, as well as their associated electronics.
