Automatic train stop

With emergency brake is called in rail transport initiated by the monitoring devices on locomotives or in the control car or by train control rapid braking of a train. It must not be equated with the initiated by the driver in dangerous situations rapid braking or with that of a passenger caused a passenger train emergency braking; from each other, this does not differ in the effect, however.

Forced stunts are triggered by the following named security systems under certain conditions:

  • A safety control ( Sifa ) ( Germany )
  • Punctual Train Control ( PZB ) ( Germany )
  • After driving past a distant signal in the position Vr 0/Ks 2 (" expect stop " ) or Vr 2 ( "Slow approach expect" ), a train control system obtained by the 1000 Hz magnet installed there and not within four seconds, the vigilance served - the operation of vigilance confirmed the driver 's perception of the signal order,
  • After receiving a 1000 -Hz interference is not a fixed, depending on the type of train PZB predetermined braking curve ( in older designs a test speed after a certain period of time ) moves below. So one has about a train (in this case with PZB90 V1.6 train type O), which runs at a speed of 160 km / h have slowed down within 23 seconds to less than 85km / h, which is continuously monitored by means of the braking curve.
  • After a train control system by a 500 -Hz magnet there the prescribed maximum or the subsequent braking curve over occurs
  • Pointing at a halt main signal passes with effective 2000 Hz magnet.
  • Within the Restrictive monitoring exceeds the specified therein zugartabhängige velocity curve (or maximum ).
  • For the PZB train type commonly prescribed speed limit exceeds significantly.
  • Linienzugbeeinflussung ( LZB ) ( Germany )
  • European Train Control System ( ETCS)
  • Speed ​​monitoring for TBV trains ( GNT ) ( Germany )
  • Other Some of the above systems are triggered when it detects own malfunctions (eg, computer failure, transmission failure ) is also an emergency brake application (and thus a failure on the safe side ).
  • Depending on the train, there are other monitoring devices, which can trigger an emergency brake application, such as diesel-hydraulic locomotives of Übertourungsschutz the transmission. Also, on vehicles with spring-loaded brake, these monitors (BR 120): the spring -loaded brake Sets while driving, so emergency brake is triggered.
