Nissan: Automatic … AWS audible indicator. Colour-light signals have a current sensing relay in the lamp lighting circuit to prove the signal alight, this is used in combination with the relay controlling the green aspect to energise the AWS electro-magnet. Background Edit. The driver then has approximately 2 seconds to cancel the warning by pressing and releasing the AWS/TPWS acknowledgement button (if a driver should collapse onto the button or keep it held down, the AWS will not be cancelled). Also, there is no automatic brake application when a stop signal is passed. For Railway operations the use is giving advance warning to drivers in-cab of approaching signals, reduction in permissible speeds and temporary/emergency speed restrictions. Noté /5. Its benefits over previous systems were that it could be used at high speed and that it sounded a confirmation in the cab when a signal was passed at clear. The Automatic Track Warning System 3000 detects trains and automatically produces a guaranteed warning for track workers by means of light and sound signals. In Germany, the Kofler system used arms projecting from signal posts to engage with a pair of levers, one representing caution and the other stop, mounted on the locomotive cab roof. It is basically an auditory warning system, with a visual display reminder.

It was found, however, that the heavy traction current could interfere with the reliable operation of the on-board equipment when traversing these routes and it was for this reason that, in 1949, the otherwise "well proven" GWR system was not selected as the national standard (see below).[10][11]. ASFA (Spanien) | Der Eisenbahnunfall von Ladbroke Grove wird wesentlich auf diese fehlende Bremsüberwachung zurückgeführt. The system works in the same way as for signals, except that a fixed magnet positioned between the running rails is located at the service braking distance before the speed reduction. Continually cancelling warnings can lead to a state of conditioning, sometimes called the "double yellow zombie" effect, where the driver fails to take appropriate action when necessary. It is possible for AWS to develop a wrong-side failure whereby the driver is given no indication or a 'clear' indication instead of a 'caution'.
